Polycentropodidae constitute 55.6% of Taimyr amber caddisfly species with known males, and only 4.8% males in Kachin amber. Micro-caddisflies obviously dominate (Archaeopolycentra, Polycentropodidae), (Palerasnitsynus, Psychomyiidae) New Jersey (Hydroptilidae); both Psychomyiidae Hydroptilidae are absent amber, rare The domination was proposed as a new characteristics Baeomorpha Realm, their ra...

Six of the 12 living orders aquatic insects contain species engaged in entomophagy, but few are being harvested effectively, leading to overexploitation and local extinction. Existing practices range from including (e.g. dipterans) core diets many indigenous peoples consumption selected as novelty food caddisflies). Comparison nutritional worth human diet domestic animal feed examined. Question...

BACKGROUND Caddisflies have significant roles in freshwater ecosystems. Morphological identification is the major impediment in accurate species identification of Hydropsychids. Mitochondrial and nuclear markers are suitable for molecular systematics of these group of arthropods. METHODS Trichopteran specimens of Lavasan District in northeastern Tehran, Iran were collected in 2012, and descri...

Anthropogenic pressures on aquatic systems have placed a renewed focus on biodiversity of aquatic macroinvertebrates. By combining classical taxonomy and DNA barcoding we identified 39 species of caddisflies from the Crooked River, a unique and sensitive system in the southernmost arctic watershed in British Columbia. Our records include three species never before recorded in British Columbia: ...
