The tropical-subtropical caddisfly genus Ugandatrichia Mosely (Hydroptilidae) is recorded from Japan for the first time, with 2 species. Ugandatrichia nakijinensis Ito sp. nov. is described from Okinawa-jima and Amami-oshima, in the south of Japan, based on adults and immature stages. Ugandatrichia taiwanensis Hsu and Chen, originally described from Taiwan, is recorded and redescribed based on ...

The male and female of a new species in the long-horned caddisfly genus Nectopsyche Müller, 1879 are described from southeastern Brazil. has genitalia similar to candida-group, but several endothecal spines phallic apparatus those gemma-group species. color pattern scales hairs on head, thorax forewings is that splendida (Navás, 1917), as both have bands metallic silver-iridescent interleaved w...

Periphyton communities of a boreal stream were exposed to different light and nutrient levels to estimate energy transfer efficiency from primary to secondary producers using labeling with inorganic (13)C. In a one-day field experiment, periphyton grown in fast-flow conditions and dominated by opportunistic green algae were exposed to light levels corresponding to sub-saturating (forest shade) ...

We present the first field observations of caddisfly (Trichoptera) larvae using an invasive alien aquatic plant, Crassula helmsii (Kirk) Cockayne, in case construction. In samples from invaded ponds across UK and Belgium, we have recorded presence C. fragments cases Limnephilus lunatus Curtis, Citation1834, marmoratus flavicornis (Fabricius, Citation1787) (Limnephilidae), Triaenodes bicolor (Cu...

A specimen of Stactobia eatoniella , a hygropetric species micro-caddisfly considered extinct in Switzerland, was discovered the Morge Valais March 2020 during routine monitoring. This last instar larva perfect condition is first to be observed Switzerland since 1944. Further research study area needed confirm presence possible well-established population. encouraging discovery should not hide ...

The general topic of this review is protein-based underwater adhesives produced by aquatic organisms. The focus is on mechanisms of interfacial adhesion to native surfaces and controlled underwater solidification of natural water-borne adhesives. Four genera that exemplify the broad range of function, general mechanistic features, and unique adaptations are discussed in detail: blue mussels, ac...

The Balkan endemic caddisfly species Drusus osogovicus Kumanski, 1980 that was previously known only from Bulgaria recently reported the Republic of North Macedonia as well. However, all data on presence included adult specimens larval stage remained unknown. In following study we present first description based morphological characters. order to prove conspecificity between larvae and adults, ...
