The faunistic knowledge of the Diptera of Morocco recorded from 1787 to 2021 is summarized and updated in this first catalogue of Moroccan Diptera species. A total of 3057 species, classified into 948 genera and 93 families (21 Nematocera and 72 Brachycera), are listed. Taxa (superfamily, family, genus and species) have been updated according to cu...

Insect-pollinated plants often release complex mixtures of floral scents to attract their pollinators. Yet scent compounds eliciting physiological or behavioural responses in pollinators have only been identified in few plant species. The sapromyiophilous aroid Arum maculatum releases a highly diverse dung-like scent with overall more than 300 diff...

Geographical variation in abundance and composition of pollinator assemblages may result in variable selection pressures among plant populations and drive plant diversification. However, there is limited knowledge on whether differences in local visitor and pollinator assemblages are the result of site-specific strategies of plants to interact with...

Bruchomyiinae is a subfamily of the Psychodidae (Diptera) with 57 extant and 19 extinct described species (Wagner & Stuckenberg, 2012, 2016). The core distribution area of extant species is the Neotropical region with almost 50 species in four genera. Six species in two genera are known from the Afrotropical region, and four species in one genus fr...

We documented and analyzed moth fly occurrence and spread of multidrug-resistant bacteria in a tertiary care hospital in Germany. The moth flies (Clogmia albipunctata) bred in the sewage system, then moved into the hospital, carrying biofilm and multidrug-resistant bacteria on their feet. Subsequently, the hospital developed a pest control protocol...

Nymphomyia allissae sp. nov. from the approximately 100 million years old Burmese amber is described and figured. The species is distinguished from other known taxa by the scimitar shaped wing, and the well sclerotized female terminalia with large cerci.

The ongoing biodiversity crisis becomes evident in the widely observed decline in abundance and diversity of species, profound changes in community structure and shifts in the species' phenology. Insects are among the most affected groups, with documented decreases in abundance up to 76% in the last 25-30 years in some terrestrial ecosystems. Ident...

Tonnoiriella Vaillant, 1971 was one of the genera not treated by F. Vaillant for his revision in Die Fliegen der paläartktischen Region.

New species described are T. aurasica sp. nov., T. i...

In the framework of a mosquito-monitoring program conducted from 2014 to 2018, non-culicid dipteran bycatch was identified to species-level with a focus on Diptera of medical and veterinary importance as part of a biodiversity initiative and barcoding project (“Austrian Barcode of Life”). Two species hitherto not known from Austria, the regularly s...

1. Rising global temperatures force many species to shift their distribution ranges. However, whether or not (and how fast) such range shifts occur depends on species' dispersal capacities. In most ecological studies, dispersal‐related traits (such as the wing size or wing loading in insects) are treated as fixed, species‐specific characteristics,...

Queenslandomyia cannula gen. nov. et sp. nov. from Queensland, and Theischingerus imbricatus gen. nov. et sp. nov. (Diptera, Psychodidae) from New South Wales, are described and figured. Queenslandomyia is characterized by the shape of the basal 4 flagellomeres with digitate lateral extensions, and an afferent sclerotized thin channel to flagellome...

Land‐use changes have degraded ecosystems worldwide. A particular concern for freshwater biodiversity and ecosystem function are stressors introduced by intensified agriculture. Typically several stressors affect freshwater ecosystems simultaneously. However, the combined effects of these multiple stressors on streams and rivers are still poorly un...

Subfamily Bruchomyiinae is comprised of 60 species and has been referred to as the most primitive within the Psychodidae. The assumed sister-group relationship with Phlebotominae is based on ecological constraints of their environment. A cladistics analysis based on 29 characters and 52 species revealed the distinction of an Old World clade charact...

Jezekiella patera, gen. et sp. nov., is described and illustrated based on a single male from Italy. Based on some character states found in this new genus (e.g. spiniform sensilla on basal flagellomeres) it is most similar morphologically to Paramormiini, a tribe that is likely paraphyletic. Other characters (e.g. allurement organs on the prothora...

In a recent paper a new subfamily of Psychodidae was inadequately named Protopsychodinae. This nomenclatural act cannot be considered as a valid name under ICZN regulations because the subfamily name is not based on the type genus Datzia Stebner et al., 2015, and furthermore the fossil genus Protopsychoda Azar et al., 1999 was originally described...

The aquatic insect collection of the late Dr. W. Joost contained two new species of Thaumaleidae (Diptera) from the Caucasus Mountains: Thaumalea monikae sp. n. and Thaumalea biacuminata sp. n.

Abundance prediction of aquatic insects (Ephemeroptera, Plecoptera, Trichoptera=EPT) based on environmental variables (precipitation, discharge, temperature) and abundance of the parent generation with Artificial Neural Nets (ANN) was carried out successfully. A general model for all species does not exist. Easy to understand models for individual...

Combined field and laboratory investigations showed that C. villosa was univoltine in the Breitenbach, Germany. Speed and duration of embryogenesis were determined by temperature. Lowest values of accumulated temperature occurred at 6 and 8°C, when the duration of embryogenesis was shortest, and egg mortality was low. Egg masses exposed at upstream...

Leaf litter is a major component in the organic matter budgets of streams worldwide. Shredding invertebrates are widely considered to be of central importance for the breakdown of allochthonous organic material in temperate-zone streams. However, various authors report an absence of this group in tropical streams. Various phenomena, including hydra...

A replacement name, Neoilliesiella is proposed for the subgenus name Heleodromia (Illiesiella) Wagner, 1985 in the fly family Empididae (Diptera).

Competing hypotheses that try to relate population size, individual weight, and water temperature in running waters were tested. Female and male dry weight and specimen numbers of eleven caddisfly species (Trichoptera) collected from 1983 to 1991 in four emergence traps along the Breitenbach (Germany) were related to site specific water temperature...

Size, weight and abundance of eleven species of caddisfly collected in four emergence traps from 1983 –1991 at the Breitenbach (Germany) were analyzed for spatial and temporal patterns. Scrapers were abundant and small, shredders rare but large, predators were in between. Individual weights of most species increased downstream. No weight change alo...

The aim of projection pursuit (PP) (Friedman and Tukey 1974, Huber 1985, Jones and Sibson 1987) is to find low (1-3)-dimensional projections showing the most interesting views of high-dimensional data. To reach this goal, many projections are calculated and rated by an objective function, a so called projection index I. Dependent on I, this method...

In 1983, about 156.000 Chironomidae in 110 taxa were recorded from two emergence traps (green-houses), one exposed above a sand substratum and another above large moss-covered sand-stones, the clearest substrata difference existing in the Breitenbach (Schlitz, Hesse, Germany). 99 species were recorded from the sand and 85 from the stone trap. Propo...

Population size of Ephemeroptera, Plecoptera and Trichoptera (EPT) emergence in a given year and the assemblage of the community are predictable based mainly on the discharge pattern of the previous year. We analysed the relationships between precipitation, discharge, water temperature and the emergence of 41 EPT species over 25 years from the Brei...
