Evaluating data quality and inventory completeness must be a preliminary step in any biodiversity research, particularly the case of insects high areas. Yet, this is often neglected or, at best, assessed only for one insect group, degree congruence sampling effort ffor different groups remains unexplored. We assess spatial distribution five (butterflies, caddisflies, dung beetles, moths, aquati...

The importance of two-way interactions between animals and the physical hydraulic sedimentological environment are increasingly recognized (e.g., zoogeomorphology). Caddisflies (Trichoptera) a group aquatic insects known for their bioconstructions, particularly cases built from fine sediment silk. Caddisfly differ in size, shape density incorporated sediment, case construction may therefore aff...

During several excursions to the Chin Hills of Myanmar from 2001 2015, rich collections caddisflies were made which form basis present taxonomic and biogeographic study. A total 106 species identified including seven new species. They are described as Arctopsyche subflava sp. nov. , Hydromanicus abdominalis Cheumatopsyche janosolahi Lepidostoma subpanaitos Aplatyphylax pumilus Adicella natmatau...

We present the first preliminary inventory of Trichoptera taxa in the Aegean and Adriatic Sea basins in Kosovo that have previously received poor and fragmentary attention. Adult caddisflies were collected using ultraviolet (UV) light traps in 13 stations in areas of the Aegean Sea and Adriatic Sea drainage basins in Kosovo. Nineteen species out of 82, reported in this article, are first record...

The limnephilid caddisfly Dicosmoecus gilvipies (Hagen) occurs in many streams of northwestern United States and British Columbia. Because of the large size of the fully grown larva, its synchronous emergence pattern, and its frequent imitation by fly-fishing anglers, D. gilvipes is one of the best known North American aquatic insects. Egg masses are found at the bases of Carex sedges. Cases of...

Land use has an important role influencing stream ecosystem processes, such as leaf litter breakdown. Here, we assessed rates of leaf litter breakdown in low-order tropical streams draining forest, agriculture, and urban land uses in Puerto Rico. To measure leaf breakdown rates, we placed litter bags made of coarse mesh in nine streams, three for each land use type. At each stream, we measured ...

Hydropower plants produce renewable and sustainable energy but affect the river’s physico-chemical characteristics change abundance composition of aquatic organisms. The impact large HPPs on ecological conditions surface water bodies have been extensively studied, less attention has paid to environmental studies small hydropower (SHPs). hydropeaking both river flow regime ecosystems well-studie...

Sublethal biological effects of heavy metals accumulated in stream macro-invertebrates were examined in larvae of two caddisflies indigenous to the Clark Fork River, Montana, Hydropsyche spp. and Arctopsyche grandis. Stress proteins, in particular members of the hsp70 family, are involved in cellular protein homeostasis and repair, and are induced by a variety of stressors, which either damage ...

Between March and November 1984, Silver Creek, a small tributary of the Mahoning River in northeastern Ohio, eroded into and through a small lacustrine deposit of glacial silt. During this erosional/ siltation episode, the stream was very turbid and siltation was observed at least 5 km below the source of silt. Only a few individuals of the caddisfly, Neophylax, the mayflies, Isonychia and Sten...

Insects of the order Trichoptera (caddisflies) are represented in Baltic amber by 22 families and comprise about 2% of all inclusions (Wichard & Weitschat 1996). Among these, the genus Rhyacophila (Rhyacophilidae) is a rare taxon presented with six so far known fossil species (Rhyacophila kutscheri Mey, 1988; R. laminata Ulmer, 1912; R. liedtkei Wichard & Caspers, 1991; R. occulta Hagen, 1856; ...
