Abstract The artificial light sources are useful tools for sampling night active insects, however, they also possess potential environmental risks in their habitats. To test applicability and evaluate risk caddisflies (Trichoptera), the attractivity of different portable traps working with LED, UV mixed-white was studied compared traditionally used mercury-vapour lamp (in Jermy-type trap), whic...

We report five new species records from the Comoros Archipelago. Two of the species are known from outside the Archipelago, Hydroptila cruciata Ulmer (Hydroptilidae) and Anisocentropus voeltzkowi Ulmer (Calamoceratidae), and three species are described as new to science: Pisulia stoltzei ,new species (Pisuliidae), and: Chimarra mayottensis, new species and Chimarra koulaeensis, new species (Phi...

Caddisflies (Trichoptera) are small, cosmopolitan insects closely related to the Lepidoptera (moths and butterflies). Most caddisflies construct protective cases during their larval development. Although the earliest recognisable caddisflies date back to the early Mesozoic (Early and Middle Triassic), being particularly numerous and diverse during the Late Jurassic and Early Cretaceous, the fir...

The objective of the study is to improve the understanding of relationships between multiple spatial scales and the development of micro-habitat as well as its co-dependence with the net-spinning caddisfly (Stenopsyche mamorada). In this study, two target riffles located in the Asa River basin were investigated during the spring of 2006. Three major findings of this research were that; 1. the t...

Systematics of the genus Itauara Müller, 1888 are reviewed. A generic diagnosis, illustrations, and descriptions are provided for males. The genus can be identified by several features of the male genitalia including an extremely reduced phallobase and a phallic apparatus that consists of a sclerotized dorsal sheath covering a very membranous ventral portion. A total 18 species are described as...
