The Dragonflies of Europe (Revised Edition)
... Libellula quadrimaculata has a Holarctic distribution and is widely distributed in Eurasia and North America (Askew, 2004;Boudot and Kalkman, 2015). The species had not been recorded so far in Turkish Thrace Region. ...
... The species had not been recorded so far in Turkish Thrace Region. While shallow ponds and lake edges with emergent vegetation have been given as the habitats where L. quadrimaculata generally breeds, it has also been reported that the species is common in the pools situated in mossy and open areas in the north of Europe (Askew, 2004). Libellula quadrimaculata was recorded from only one location, a bushy area in at the border of a swampy area near the edge of the Meriç River about 7 or 8 km inwards from the shore of the Aegean Sea. ...
... Libellula quadrimaculata was recorded from only one location, a bushy area in at the border of a swampy area near the edge of the Meriç River about 7 or 8 km inwards from the shore of the Aegean Sea. Since this species could not be found in any of our other sampling sites, neither along the river nor in other water bodies in the delta, we conclude that it is not likely for L. quadrimaculata, known as a vagrant and migrant species (Askew, 2004), to be native in our study area, so that this record most likely belongs to a vagrant individual. Libellula quadrimaculata is known from Greece (Lopau, 2010) and might occur in the Evros Delta, which is the part of the Meriç Delta in Greece. ...
This study was performed in the Meriç Delta located in the Edirne province of the Turkish Thrace Region in order to reveal the diversity and distributions of odonates in the delta wetlands. Samplings were performed from spring to autumn in 2014 and 2015 in different wetland localities represented by lagoons, lakes and a river. A total of 30 Odonata species were recorded during the study, of which Libellula quadrimaculata is a new record for both the study area and Turkish Thrace. In addition, Calopteryx splendens (Harris, 1780), Lestes dryas Kirby, 1890, Lestes macrostigma (Eversmann, 1836), Coenagrion puella (Linnaeus, 1758), Coenagrion pulchellum (Vander Linden, 1825), Coenagrion scitulum (Rambur, 1842), Enallagma cyathigerum (Charpentier, 1840), Ischnura pumilio (Charpentier, 1825), Aeshna affinis Vander Linden, 1820, Aeshna isoceles (Müller, 1767), Anax imperator Leach, 1815, Lindenia tetraphylla (Vander Linden, 1825), Libellula depressa Linnaeus, 1758, Libellula fulva Müller, 1764, Orthetrum brunneum (Fonscolombe, 1837) and Sympetrum meridionale (Selys, 1841) are the species determined to be new records for the Meriç Delta wetland. While the Odonata fauna of the Meriç Delta was represented so far by 14 species, this number increased to 31 with the addition of 17 new species during this study. The diversity of the Odonata species recorded in the delta and their conservation categories according to the Red List criteria of the World Conservation Union (IUCN) are also considered.
... A record from Kiskunság in Hungary published by Steinman (1986) is doubtful and is here regarded as incorrect. The occurrence of the species in Romania and Ukraine indicated by the map in Askew (1988Askew ( , 2004 is incorrect. ...
... In some years the migration reaches central and northern Europe and on these occasions it can turn up anywhere in Europe, reaching as far north as Iceland (see above). Recent years with large numbers of migrants include (Dumont & Desmet 1990, Burbach & Winterholler 1997, Askew 2004, Parr 2011, SFO 2013. The direction and probably the origin of the invasions varies between years, with the event of 1995 resulting in high numbers mainly in northern Anatolia ) and central Europe (Burbach & Winterholler 1997), and that of 2011 mainly noted in western Europe, particularly along the Atlantic coast and the nearby landmass (SFO 2013). ...
... The species was one of the last to have been recognised in Europe (Ferreras-Romero 1989). However it was not a recent arrival, as shown by the presence in the Museo Nacional de Ciencias Naturales in Madrid of several specimens collected in November 1900 at Cartagena (Murcia), in August 1906 at Gava and Antiga (Barcelona), in September 1910 at Oliete (Teruel) and in August 1961 at Úbeda (Jaen) (Askew 2004, Paris et al. 2014. Field work in the past two decades has shown this species to be fairly common in parts of eastern Spain, although less common in the south of the country (Jödicke 1997b). ...
This work is the first detailed and comprehensive overview of the distribution of the dragonflies and damselflies of Europe. It is an important milestone for professionals and amateurs alike. Covers the distribution and habitat selection of all 143 European species of dragonflies and damselflies. Gives a complete description of their global and European distribution, illustrated by over 200 distribution maps. Gives for each species information on taxonomy, range, population trends, flights season and habitat. Includes unique photos and flight season diagrams for virtually all European species. Contains extensive background information on taxonomy, conservation, and for each country an overview of the history of odonatological studies. The book is the result of a co-operation of over 50 European dragonfly experts who over the past decade compiled all records of dragonflies and damselflies, from the Azores to the Ural and from the North Cape to Lampedusa. These records were gathered by thousands of volunteers from across Europe. This endeavour was coordinated by Jean- Pierre Boudot (Société Française d’Odonatologie) and Vincent Kalkman (European Invertebrate Survey – Netherlands/Naturalis Biodiversity Centre).

... Gomphus pulchellus is an endemic species in western Europe, regularly and often abundantly occurring on the Iberian Peninsula, in France, Belgium, Switzerland, the Benelux countries, and the western part of Germany (Askew 2004; Dijkstra & Lewington 2006). A growing number of records during the last decades indi-cate that it tends to expand its range eastwards (e.g., Rudolph 1980; Monnerat 2005; Buczyński et al. 2013; Suhling in press). ...
... However , recently a record of the larva of G. pulchellus was reported from Montenegro (Buczyński et al. 2013) which may indicate a viable population, though further confirmation would be desirable. Gomphus pulchellus is also reported from Slovakia (Dudich 1958), Romania (Platttner 1968), and Macedonia (Beschovski 1994), but these records are given without any verifiable evidence or they were erroneous or considered doubtful (Suhling & Müller 1996; Askew 2004; Buczyński et al. 2013). The same is true for a former record reported from South Bohemia by Flíček (2000) although it is incorporated in the recent Czech highly detailed dra gonfly monograph (Dolný et al. 2007). ...
One male of Gomphus pulchellus was recorded and photographically documented on 08 June 2014 near the township Lány, ca 40 km west of Prague.

In this paper we present data on damselflies and dragonflies (Insecta: Odonata) of the Landscape of outstanding features (LOF) "Vlasina". Most of the data were collected during research camps of the Scientic Research Society of Biology and Ecology Students "Josif Pančić" that took place from 2013 to 2018, when 27 Odonata species were recorded. If this research is combined with previously published data, 37 species of damselflies and dragonflies were recorded in Landscape of Outstanding Features "Vlasina". The paper presents distribution and reproduction status of the recorded species, as well as their diversity in this area. The most important species is Epitheca bimaculata (Charpentier, 1825), because Vlasina represents one of its southernmost and highest habitats in Europe. For Sympetrum flaveolum (Linnaeus, 1758) Vlasina is one of the most important habitats in Serbia, as well as for Leucorrhinia pectoralis (Charpentier, 1825) which is Natura 2000 species.

... In this study, we explore predator selection on wing shape and coloration in males of the banded demoiselle Calopteryx splendens (Harris, 1782), a riverine damselfly (Askew, 2004). A territorial Calopteryx male defends a small river patch that contains a perch and oviposition substrate for females (Heymer, 1972(Heymer, , 1973. ...
Wing shape is related to flight performance, which is expected to be under selection for improving flight behaviours such as predator avoidance. Moreover, wing conspicuousness, usually involved in sexual selection processes, is also relevant in terms of predation risk. In this study, we examined how predation by a passerine bird, the white wagtail Motacilla alba, selects wing shape and wing colour patch size in males of the banded demoiselle Calopteryx splendens. The wing colour patch is intra- and intersexually selected in the study species. In a field study, we compared wings of live damselflies to wings of predated damselflies which are always discarded after predation. Based on aerodynamic theory and a previous study on wing shape of territorial tactics in damselflies, we predicted an overall short and broad wing, with a concave front margin shape to be selected by predation. This shape would be expected to improve escaping ability. Moreover, we predicted that wing patch size should be negatively selected by predation. We found that selection operated differently on fore- and hindwings. In contrast to our predictions, predation favoured a slender general forewing shape. However, the predicted wing shape was favoured in hindwings. We also found selection favouring a narrower wing colour patch. Our results suggest different roles of fore- and hindwings in flight, as previously suggested for Calopteryx damselflies and shown for butterflies and moths. Forewings would be more involved in sustained flight and hindwings in flight manoeuvrability. Our results differ somehow from a recently published work in the same study system, but using another population, suggesting that selection can fluctuate across space, despite the simplicity of this predator-prey system.

... Back in the laboratory, individuals were sorted and stored in 70% ethanol. The macroinvertebrates were identified to the family level using a Leica MZ12 stereoscope (Leica Microsystems, Wetzlar, Germany) and the appropriate dichotomous keys [9][10][11][12][13]. Finally, the Biological Monitoring Working Party (BMWP) score [14], the Average Score Per Taxa (ASPT) [15], the Lincoln Quality Index [16], the Iberian BMWP and the Iberian ASPT [17] were applied to the benthic macroinvertebrate samples to assess the water quality of each site. ...
Biotic indices are commonly used in biomonitoring
programs to assess the quality of surface waters. In the
present study, a number of biotic indices based on benthic
macroinvertebrates have been applied in assessing
the water quality of a mountainous stream (Pelion, Central
Greece). Samplings were done in summer and autumn
2012 in two sampling sites (Karamani, Servanates)
using two sampling methods: (a) a standard pond net and
(b) the Surber method. Invertebrate identification was performed
to the family level. The Biological Monitoring
Working Party (BMWP) score, the Average Score Per Taxa
(ASPT), the Lincoln Quality Index, as well as the Iberian
BMWP, and the Iberian ASPT were applied to the benthic
macroinvertebrate samples to assess the water quality of
each site. According to ASPT, IASPT and LQI, the biological
water quality of both sampling sites was very good,
regardless of the season and the sampling method used,
with the exceptions of the summer samplings in Servanates
with both sampling methods, and in Karamani with
Surber, for which a good water quality was assessed with
LQI and IASPT, respectively. In contrast, the BMWP and
IBMWP scores for the sampling site Servanates were low,
corresponding to fair water quality, but this effect was
attributed to the particular hydrological conditions of this
site. The sampling method did not significantly affect the
sampling efficiency and, consequently, the results of the
water quality evaluation.

Presence of Macromia splendens (Pictet, 1843) (Odonata: Corduliidae) in the Tranco de Beas reservoir (Jaén)
... Within this large clade, it stands out by the males having a spur that springs from the ventral base of the superior appendage or cercus (see e.g. Askew, 2004), a character it shares with the genus Chromagrion (and Teinobasis), but not with Ceriagrion (De Marmels, 2007 The range of Pyrrhosoma consists of two disjunct parts. The western branch extends from a nucleus in the Atlas Mountains in North Africa in the West, across Western Europe eastwards as far as Moscow, narrowly reaching the southern Urals in Bashkhiristan (see Skortsov, 2010, for a map). ...
The placement and relationships of the red-and-black zygopteran Pyrrhosoma, currently considered to be part of the Teinobasinae, has long been uncertain. DNA fragments (COI and ITS) reveal that Pyrrhosoma s.s. is restricted to the West Palaearctic, with two morphologically distinct name-bearing clades (nymphula, elisabethae), and with a morphologically indistinct third clade in the Middle Atlas, Morocco, that might be close to the common ancestor of all three. Chromagrion, the closest relative of Pyrrhosoma, is found in North America, not in South Asia. Two isolated Chinese taxa (tinctipenne and latiloba) are morphologically similar to Pyrrhosoma, but their molecular distance is so large that a new genus, Huosoma, is required to accommodate them. Past climate change is suggested as the driver of the biogeography and evolution of this group of zygopterans. The origin of the Moroccan isolate and of elisabethae might predate the glaciations, and be of Pliocene age. The much wider disjunction between the American and South Asian groups and the western group suggests an older, perhaps Miocene age.
... The identifications of species were based on CONCI & NIELSEN (1956), ASKEW (2004), d'AGUILAR et al. (1985, DIJKSTRA & LEWINGTON (2006) and DUMONT (1991). ...
Mainly within the last ten years, the number of species of Odonata known from the Maltese Islands has increased from nine resident and two migrant species to 13 res-idents and two migrants. The former migrant species now regularly breed in the is-lands. The literature on the Odonata of Malta is reviewed, and an overview of the flight season data is given. Records of all species are given for the first time and some reasons for the recent increase in the number of species are discussed.

... Ischnura elegans is among the most common damselfly species in Europe [50,51]. The species is best known for its heritable female-limited colour polymorphism [7] . ...
Background
Sexual conflict over mating rates may favour the origin and maintenance of phenotypes with contrasting reproductive strategies. The damselfly Ischnura elegans is characterised by a female colour polymorphism that consists of one androchrome and two gynochrome female morphs. Previous studies have shown that the polymorphism is genetic and to a high extent maintained by negative frequency-dependent mating success that varies temporally and spatially. However, the role of learning in male mating preferences has received little attention. We used molecular markers to investigate differences in polyandry between female morphs. In addition, we experimentally investigated innate male mating preferences and experience-dependent shifts in male mating preferences for female morphs.
Results
Field and molecular data show that androchrome females were less polyandrous than gynochrome females. Interestingly, we found that naïve males showed significantly higher sexual preferences to androchrome than to gynochrome females in experimental trials. In contrast, experienced males showed no preference for androchrome females.
Conclusions
The ontogenetic change in male mate preferences occurs most likely because of learned mate recognition after experience with females, which in this case does not result in a preference for one of the morphs, but rather in the loss of an innate preference for androchrome females.
Simple Summary
Two species of Sympetrum, namely S. depressiusculum and S. frequens, have been documented in South Korea. However, the distinction between these two species and their identity within South Korean populations has been a longstanding point of contention. To solve this issue, morphology, two mitochondrial genes, and one nuclear region were analyzed for S. depressiusculum samples from The Netherlands and Russia and S. frequens samples from Japan, as well as samples of Sympetrum from South Korea. Further, available public sequence data for the two species were included. Morphology, sequence divergence, and phylogenetic results all consistently suggest that South Korean populations form a single species. Analyses of haplotype network and gene pool distribution patterns in a nuclear region conducted to better explain the current taxonomic implications indicated changes in the dominant gene pool from The Netherlands and Russia to South Korea and Japan. However, such divergence and subdivision could be explained within the context of within-species diversification patterns, suggesting that South Korean populations constitute one species, S. depressiusculum, by applying the senior name.
Abstract
In South Korea, both Sympetrum depressiusculum Sélys, 1841 (Odonata: Libellulidae), which is distributed throughout Europe and from Russia to the Korean Peninsula, and Sympetrum frequens Sélys, 1883, which is endemic to Japan, are recorded. However, the identity of South Korean populations and the validity of listing the two species have not yet been settled. In this study, we collected seventy-four individuals of Sympetrum species from South Korea (five localities), Russia, The Netherlands, and Japan. These samples were examined for morphology and sequenced for partial COI, 16S rRNA, and a nuclear internal spacer (ITS) region, after which these molecular data were combined with available public data from Russia, Japan, and The Netherlands. Major morphological characters that have been used to distinguish the two species and phylogenetic, network, and structure analyses all consistently suggest that South Korean populations form a single species. Consequently, it could be valid to treat South Korean populations as one species, S. depressiusculum, by applying the senior name. Nevertheless, the validity of maintaining each as an independent species in other countries may need additional study considering that our samples were focused more on South Korea and limited for Europe, Russia, and Japan.

Mapping Priority Areas for Connectivity of Yellow-Winged Darter (Sympetrum flaveolum, Linnaeus 1758) under Climate Change. Land 2023, 12, 298. Abstract: The yellow-winged darter (Sympetrum flaveolum Linnaeus, 1758, Odonata), which is associated with high mountain areas, can be considered a flagship species. Due to climate change, its natural range will be negatively affected. In this study, we propose global potential distributions for this species up to the year 2100, considering four time periods (2021-2040, 2041-2060, 2061-2080, and 2081-2100) and three shared socioeconomic pathways (optimistic-SSP245, middle of the road-SSP370, and worst-SSP585), by using an ecological niche model to produce two sets of distribution models (80% to 100% and 60% to 100%). It is foreseen that in the worst of the considered climate scenario (SSP585-2100 year), the distribution of this species could be reduced by almost half, which could pose a risk for the species and provoke the shift from vulnerable to endangered. An analysis of connectivity has also been carried out for all the studied scenarios by applying the MSPA and PC indices, showing that the core habitat of this species will become more important, which is consistent with the decrease in the distribution range. Over time, the importance of the most valuable connectors will increase, implying a greater risk of some populations becoming isolated.
The F0 larval morphology and exuviae of Calopteryx xanthostoma (Charpentier, 1825),
(Odonata: Calopterygidae)
Because of the genetic study of the genus Calopteryx Leach, 1815, in the paleartic fauna
Calopteryx xanthostoma (Charpentier, 1825) and Calopteryx splendens (Harris, 1782),
have been separated. Both species can be easily distinguished in their adult specimens;
however, the same does not apply to their larvae.
There are few bibliographic references to C. xanthostoma larvae and, at present, no
morphological criteria have been proposed to allow a clear separation between these two
species in their larval level. In this paper a morphological study of larvae F0 and exuviae
C. xanthostoma seeks to alleviate this lack of information.
In 2008 and 2009 the odonate species Southern Damselfly Coenagrion mercuriale, Keeled Orthetrum Orthetrum coerulescens and Southern Orthetrum Orthetrum brunneum were explored near Halberstadt in the northeastern Harz Foreland (Sachsen-Anhalt). Information about the occurrence, phenology and biology of the species are given.
Reproduction by copulation and ovipositing were proved, also newlyemerged adult dragonflies. The occurrences of dragonflies are affected by intensive maintenance of water and banks. In addition the habitat was reduced by destroying of break down lane by agricultural use. Proposals for necessary precautions are given.
Se ha registrado la presencia de Anax ephippiger (Burmeister, 1839) en tres localidades de la provincia de Cuenca (este de España).
First record of Anax ephippiger (Burmeister, 1839) (Odonata: Aeshnidae) from Cuenca province (eastern Spain) Abstract: The presence of Anax ephippiger (Burmeister, 1839) in three localities in Cuenca province (eastern Spain) is reported.
Using a combination of computer simulations and laboratory experiments we test if the thermal sensitivity of growth rates change during ontogeny in damselfly larvae and if these changes can be predicted based on the natural progression of average temperature or thermal variability in the field. The laboratory experiment included replicated species from Southern, Central, and Northern Europe. Although annual fluctuations in temperature represent a key characteristic of temperate environments, few studies of thermal performance have considered the ecological importance of the studied traits within a seasonal context. Instead, thermal performance is assumed to remain constant throughout ontogeny and to reflect selection acting over the whole life cycle. The laboratory experiment revealed considerable variation among species in the strength and direction of ontogenetic performance shifts. In four species from Southern and Central Europe, reaction norms were steepest during early ontogeny, becoming less steep during later ontogenetic stages (indicative of low-temperature acclimation). In one Northern European species, the slope of reaction norms did not change during ontogeny. In the other North European species, reaction norms became steeper during ontogeny (indicative of high-temperature acclimation). We had expected high-latitude species to show strong low-temperature acclimation responses, because they have a short flight season and inhabit a strongly seasonal environment. Instead, we found the reversed pattern: Low-latitude species displayed strong low-temperature acclimation responses, and high-latitude species displayed weak, or even reversed, acclimation responses to low temperatures. These findings suggest that low-temperature acclimation may be less beneficial and possibly more costly in habitats with rapid seasonal transitions in average temperature. We conclude that thermal performance traits are more dynamic than typically assumed and caution against using results from single ontogenetic stages to predict species' responses to changing environmental conditions.

Spain Summary 1. Female-limited colour polymorphism is very common in odonates. One of the forms has male-like colouring (androchromotypics), while the other(s) is cryptic (gynochromotypics). Three hypotheses have been proposed to explain the main-tenance of this polymorphism: (1) higher reproductive isolation of androchromo-typics, balanced by higher predation on this form; (2) androchromotypics avoid unnecessary long matings, but suffer greater predation; and (3) androchromotypics avoid male harassment at high density, but have lower mating success at low density. 2. To test these hypotheses I measured survivorship and mating success of andro-and gynochromotypic females of Ischnura graellsii in two natural populations with different densities in Galicia (NW Spain). 3. Contrary to the predictions of hypotheses 1 and 2, mean longevity and daily survival rate was the same for andro-and gynochromotypics. 4. Mating success was the same for andro-and gynochromotypics at high density but the proportion of unmated females was greater in andro-than gynochromotypics at low density. Furthermore, androchromotypics mated with longer inter-copula intervals at high density, and mating duration was also density-dependent. These results suggest that hypothesis 3 is the most appropriate to explain the maintenance of the polymorphism. 5. Androchromotypics were larger than gynochromotypics in the high density population. As body size is related to larval nourishment, this suggests an effect of larval competition on the maintenance of polymorphism. 6. It is proposed that both the mating behaviour of this species (long copulations) and the existence of changes in population density during the season are the main factors that maintain the polymorphism in I. graellsii.

First record of the threatened damselfly Coenagrion scitulum (Odonata: Coenagrionidae) in Teruel province (Spain)
Spatial genetic structure (SGS) is largely determined by colonization history, landscape and ecological characteristics of the species. Therefore, sympatric and ecologically similar species are expected to exhibit similar SGSs, potentially enabling prediction of the SGS of one species from that of another. On the other hand, due to interspecific interactions, ecologically similar species could have different SGSs. We explored the SGSs of the closely related Calopteryx splendens and C. virgo within Finland and related the genetic patterns to characteristics of the sampling localities. We observed different SGSs for the two species. Genetic differentiation even within short distances in C. splendens suggests genetic drift as an important driver. However, we also observed indication of previous gene flow (revealed by a negative relationship between genetic differentiation and increasing potential connectivity of the landscape). Interestingly, genetic diversity of C. splendens was negatively related to density of C. virgo, suggesting that interspecific interactions influence the SGS of C. splendens. In contrast, genetic differentiation between C. virgo sub-populations was low and only exhibited relationships with latitude, pointing to high gene flow, colonization history and range margin effects as the drivers of SGS. The different SGSs of the two ecologically similar species cautions indirect inferences of SGS based on ecologically similar surrogate species.This article is protected by copyright.

Gomphus graslinii (Rambur, 1844) is a threatened species included in the Spanish Checklist of Endangered Species and in the Habitats Directive of the European Union. Its Iberian distribution is very fragmented, with scarce populations and records published from the northeastern quadrant, including two records of adult specimens in Navarra. We searched for this species in 23 reaches of Pre-Pyrenean rivers from Eastern Navarra, and provide date on its reproduction in two reaches of Salazar River. Moreover, other 24 dragonfly species have were found, including Gomphus simillimus Selys, 1840 and Coenagrion caerulescens (Fonscolombe, 1838), both considered as Vulnerable
in the Atlas and Red Book of the Invertebrates of Spain.
Conservation status and Spanish distribution of threatened invertebrate species is evaluated. Distribution, life cycles and species biology rewieved. In this chapter, Coenagrion caerulescens situation in Spain is analysed and mapped.
Confirmation of the presence of the threatened dragonfly Oxygastra curtisii (Dale, 1834) (Odonata: Corduliidae) in Asturias (N Spain)
_____________________________________________________________ ABSTRACT The present work aims to contribute to and compare existing knowledge on Odonata species occurring in the Maltese Islands by providing additional records collected between the years 2000-2008.
During the period 1987-1988 a Calopteryx specimen was found dead in a rock pool at Marsascala. This was a first record of this genus on the Maltese Islands. In this paper we discuss the possibilities of its occurrence and our conclusion to the identification of the specimen as Calopteryx virgo meridionalis.
Conservation status and Spanish distribution of threatened invertebrate species is evaluated. Distribution, life cycles and species biology rewieved. In this chapter, Gomphus simillimus situation in Spain is analysed and mapped.
A larva from the Zeta river (Danilovgrad, 12-X-2010) is brought on record, figured and its habitat is described. This is the first record of G. pulchellus larva from the Balkans. The eastern records of the sp. are reviewed and mapped, and the eastern range of G. pulchellus is discussed.
Teratologies in adults of Calopteryx Leach, 1815 (Odonata: Calopterygidae)
Several teratologies are described in adult specimens of Calopteryx virgo meridionalis, C. xanthostoma and C. haemorrhoidalis. These teratologies are mainly associated with the wing pigmentation but also with the abdomen.
Se describen varias teratologías en ejemplares adultos de Calopteryx virgo meridionalis , C. xanthostoma y C. haemorrhoidalis. Éstas afectan al abdomen y sobre todo a la pigmentación de las alas.
Intraspecific body colour variation is common in many animal species. Predation could be a key selective agent giving rise to variation in body colour, and such variation could be due to genetics (polymorphisms) or phenotypic plasticity (polyphenisms). In this study we examined the degree of colour polymorphism and polyphenism in background colour matching in larvae of the damselfly Coenagrion
armatum. In addition, we tested if predation risk is reduced when larvae are exposed to a matching compared to a non-matching background. By raising families of larvae at three different background colours we showed that polymorphism explained about 20 % of the total variation and polyphenism about 35 %. In a predation experiment with fish, we showed that larvae with a body colour matching the background had a higher survival success compared to larvae with a non-matching background colour. We suggest that the background matching is adaptive in terms of survival from predation and that colour diversity is maintained because of spatial and temporal variation in the background experienced by damselfly larvae under field conditions.
La vulnerabilidad de las libélulas se pone de manifiesto en el hecho de que, de las 5.600 especies reconocidas en el mundo, 176 han sido incluidas en alguna categoría de amenaza en la Lista Roja de la UICN de 2006. Un reciente estudio [3] siguiendo los criterios de valoración del riesgo de extinción de la UICN concluye que un 10% de las libélulas evaluadas (1.500 especies) se encuentra amenazada, ya sea en las categorías de en peligro crítico (2%), en peligro (3%) o vulnerable (5%). En el caso de la Península Ibérica, de las 78 especies presentes, 18 se encuentran recogidas en el reciente Libro Rojo de los Invertebrados de España [4]. En este artículo divulgativo expondremos la situación de las cuatro especies amenazadas asociadas a hábitats de montaña en la Península Ibérica (Aeshna juncea, Cordu-legaster bidentata, Sympetrum flaveolum y Leucorrhinia pectoralis).

Cordulegaster heros Theischinger, 1979 is a Natura 2000 species of community importance and the only strictly protected dragonfly in Hungary. Occurrences of the species in Hungary are still known from Sopron Mountains, Őrség and Mecsek. More recently it has been collected in Zselic Hills and Kőszeg Mountains. Conservation and protection of the breeding habitats of the C. heros are important due to the species is rare and endangered. In this study we discuss the results of collections carried out between 2008 and 2010. New faunistical records are given for 468 individuals of C. heros from 69 sampling sites of Mecsek Mountains and its surroundings.

Dragonfly communities from the upper-middle basin of the Tâmega River (north-eastern Portugal) (Insecta: Odonata) Abstract: The Odonata communities of the upper-middle basin of the Tâmega river (Portugal) were analysed by sampling of adults and exuviae in 2010 and 2011. Thirty-seven dragonfly species were found, which account for half of those known from the Iberian Peninsula and 60% of the Portuguese species. The most frequent species in the area were Calopteryx virgo, Cordulegaster boltonii, Boyeria irene, Anax imperator, Pyrrhosoma nymphula, Platycnemis latipes, Onychogomphus uncatus, Calopteryx xanthostoma and Orthetrum coerulescens. Furthermore, large populations of Macromia splendens, Oxygastra curtisii and Gomphus graslinii, protected species included in Habitats Directive, were frequent in the area. Coenagrion mercuriale, another protected species, presented a more restricted distribution in the study area.
---------------------------------------
Durante 2010 y 2011 se han estudiado las comunidades de odonatos de la cuenca media-alta del río Támega en Portugal, realizándose tanto muestreos de adultos como de exuvias. Se han encontrado 37 especies de odonatos, que representan la mitad de las encontradas en la Península Ibérica y el 60% de las portuguesas. Si bien las especies más frecuentes han sido Calopteryx virgo, Cordulegaster boltonii, Boyeria irene, Anax imperator, Pyrrhosoma nymphula, Platycnemis latipes, Onychogomphus uncatus, Calopteryx xanthostoma y Orthetrum coerulescens, cabe destacar las grandes poblaciones de Macromia splendens, Oxygastra curtisii y Gomphus graslinii, especies protegidas por la Directiva Hábitats que son relativamente frecuentes y abundantes en la zona, y Coenagrion mercuriale, con una distribución más restringida en el área de estudio e igualmente protegida.

The paper presents a list of 258 Odonata specimens collected during the expeditions carried out in Western Turkey between 2005-2006 by the "Grigore Antipa" National Museum of Natural History. In all, 27 Odonata species were identified, grouped in nine families. The paper also presents some distributional data for these 27 species. Résumé. Le travail présente une liste de 258 exemplaires d'Odonates collectés au cours des expéditions organisées à l'ouest de la Turquie au cours des années 2005 et 2006 par le Muséum National d'Histoire Naturelle «Grigore Antipa». En tout, on a identifié 27 espèces d'Odonates groupées en neuf familles. On présente aussi quelques données sur la distribution de ces 27 espèces.
Based on literature and on the 2002-2005 surveys, 54 spp. are listed from 43 localities. New records are provided for 43 spp. Coenagrion scitulum and Sympetrum pedemontanum are new to the region. The occurrence of Calopteryx splendens ancilla on the lower Danube (cf. A.N. Bartenev, 1912, Ezhegod. zool. Muz. imp. Akad Nauk 17: 281-288) is confirmed. Erythromma lindenii, hitherto known from the lower Danube, is recorded also from the Dnieper and Dniester basins. The SW Ukrainian populations of Orthetrum coerulescens are referable to O. c. anceps.
Check-list of Odonata of Aragon Bibliographical records from Aragon are critically reviewed. There are 58 spp in the check-list (24 Zygoptera, 34 Anisoptera). Four spp are removed (Coenagrion pulchellum, Platycnemis pennipes, Paragomphus genei, Sympetrum depressiusculum). The avaliable distribution data are mapped on a UTM 10x10 km grid.
