The decline of pollinators in agricultural environments poses a significant threat to pollination ecosystem services. Wildflower strips are proposed as a strategy to support pollinator populations and enhance their species richness and diversity. We investigated the efficacy of flowering plant mixture in maintaining aculeate pollinator diversity (w...
Cuckoo wasps, also known as jewel or gold wasps (Hymenoptera: Chrysididae), are kleptoparasites and parasitoids that impose their offspring on the breeding efforts of other wasp species. Chrysidids oviposit in the nests of predatory wasps, and the hatched larva kills the host's larva and consumes the resources collected by the host. When a cuckoo w...
Upon exploring the mitotype diversity of the aphid-hunting wasp, Diodontus tristis, we revealed specimens with highly divergent mitotypes from two localities in Lithuania and nesting in clayey substrate, while the specimens with typical mitotypes were found nesting in sandy sites. The comparison of inter- and intra-specific distances and applicatio...

The aim of the study was to clarify the phylogenetic relationships among Northern European Ancistrocerus and comparison of the applicability of evolutionarily neutral and non-neutral markers for reconstruction of phylogeny. We used a 19,400 bp long dataset that included parts of mitochondrial DNA, nuclear rDNA operon, and 10 nuclear protein-coding...
The article presents new data on two southern bee species: Anthidium oblongatum (Illiger, 1806), Megachilidae, found for the first time in Lithuania, and Xylocopa valga (Gerstaecker, 1872), Apidae, which disappeared almost 80 years ago. Places and dates of capture or observations of both species, number of individuals and their sex, observers or co...

A gynandromorph is an organism combining both female- and male-type tissues. While the vast majority of studies have described the morphology of gynandromorphs, their sexual behaviours remain under-explored. We studied a predominantly bilateral gynandromorph specimen of the predatory wasp Discoelius dufourii (Hymenoptera: Vespidae: Zethinae) reared...

Two new species of Diodontus Curtis, 1834 (Hymenoptera: Pemphredonidae) are described. Diodontus polytylus Budrys new species is widespread in North Africa, from Libya and Chad to Morocco, as well as in southern Spain and Portugal. Diodontus guichardi Budrys new species was found in several localities in Morocco. The new species have small differen...
Insect guts are colonized by different species of microorganisms, most of which are benign or beneficial to their host. However, little is known about how the microbial gut communities vary among different host species. In this study, using 16S metagenomic sequencing, we compared the indigenous gut microbiota in adult of two solitary cavity-nesting...

Kiekvienai šių vapsvų rūšiai pateikiamos sugavimo vietos ir datos, individų skaičius bei jų lytys, ri...
Cryptic species complexes cause major challenges for taxonomists and alter understanding of species diversity. In Northern Europe, the Chrysis ignita species group is one such complex with numerous sympatric sibling species. The objective of this paper is to assess the taxonomy of 15 species from this group using three different approaches: molecul...
Lietuvoje aptikta 15 Pepsinae pošeimio voravapsvių (Pompilidae) rūšių iš visų 5 šios grupės genčių, aptinkamų Šiaurės Europoje. Miško buveinėse eksponuotose lizdavietėse-gaudyklėse plėviasparniams vabzdžiams viena iš gausiausiai apsigyvenančių rūšių yra miškinė voravapsvė (Dipogon subintermedius); kitos dvi dažnos rūšys – dvijuostė (D. bifasciatus)...
Abstract Solitary trap-nesting wasps are prospective bioindicators of anthropogenic pressures on natural ecosystems and one of the surrogate taxa for biodiversity assessments. The implementation of these studies is taxonomy-based and relies on accurate identification of species. The identification of larval stages of cavity-nesting Hymenoptera, col...
Sex-specific patterns of individual growth, resulting in sexual size dimorphism (SSD), are a little studied aspect of the ontogeny related to the evolutionary history and affected by the ecology of a species. We used empirical data on the development of the predatory wasp Symmorphus allobrogus (Hymenoptera, Vespidae) to test the hypotheses that sex...
Solitary cavity-nesting Hymenoptera constitute a group of important bioindicators of terrestrial habitats. Some of them, like caterpillar-hunting potter wasp Ancistrocerus trifasciatus (Hymenoptera: Vespidae: Eumeninae), are quite abundant in both continuous and fragmented habitats and might be a promising model species for studying the impact of h...
The stinging pattern of a predatory wasp is a behavioural trait, affecting the possible evolutionary changes of its niche, e.g. widening or shifting the prey spectrum. We tested the hypothesis that the ability of a predator to adjust its handling effort to the size of prey is a species-specific trait, the parameters of which depend on the size and...

The application of trap-nests for the studies of cavity-nesting Hymenoptera eventually implies a need for immediate nest identification using its structure. Possible nest characters that may be potentially useful for the separation of closely related species are body size-dependent metrical parameters of brood cells. We studied the dependence of br...
This paper represents an initial attempt to examine mating phases of ten wasp species of the genera Ancistrocerus, Discoelius and Symmorphus, posing the questions as to what species traits are potentially involved in interactions between sexes, and what forms of sexual selection impel the evolution of these traits. The studied species significantly...
Eight species from three genera of predatory wasps (Hymenoptera: Vespidae: Eumeninae) were studied to establish how their stinging effort depends on prey weight, the number of prey specimens in a brood cell and the nesting cavity width as an indirect measure of wasp size. The number of delivered stings was weakly positively dependent on the victim'...
Ancistrocerus, Discoelius and Symmorphus are xylicolous predatory wasps, the former two genera hunting caterpillars, the last one using both caterpillars and larvae of Chrysomelidae beetles. One of the aims of this study was to compare the stinging pattern of species from these genera with the ancestral "complete four-sting pattern" (C4SP) and redu...
Symmorphus allobrogus (Saussure) (Hymenoptera: Eumeninae) is a solitary wasp hunting the larvae of Chrysomelidae. Sting traces on 3,210 paralysed prey specimens were studied. In over 50% of the cases, the wasp directed 6ñ9 stings (average 8.7) to 4ñ6 (average 5.1) body segments of the prey. Usually stings were applied to the throat, thoracic segmen...
For the first time in Lithuania the mark-release-recapture (MRR) method was applied for assessment of the insect population size. We evaluated abundance of model populations of species from the orders Orthoptera (Metrioptera bicolor, Platycleis albopunctata, Oedipoda caerulescens, Psophus stridulus, Sphingonotus caerulans), Hymenoptera (Symmorphus...
Elements of the predatory wasp Symmorphus allobrogus mating behaviour are described, their influence on mating success is assessed based on laboratory observations. The analysis revealed that in the premounting phase activities of males, abdomen extension and substrate antennation, in particular, play a decisive role in predetermining mating succes...
The study has been carried out during the years 1989-2002 in five localities of Lithuania, using bundles of 25-35 internode fragments of Phragmites australis stems as trap-nests. We obtained 3237 nests of 33 identified solitary wasp and bee species. The dominant species were as follows: Symmorphus allobrogus (2030 nests), Ancistrocerus antilope (26...
The studied populations of six solitary predatory wasps of the subfamily Eumeninae show a different degree of prey choice specificity. Symmorphus murarius and S. crassicornis may be considered as nearly monophagous, hunting only larvae of Chrysomela and sometimes closely related Linaeidea. S. allobrogus provisions its nests mainly with prey of Chry...
