Structure and distribution of antennal sensilla were studied in males 19 species the caddisfly family Hydropsychidae by using scanning electron microscopy (SEM). Eleven types found: long trichoid, chaetoid, thick curved coronary, basiconic, styloconic four pseudoplacoid (mushroom-like, auricillic, ribbed, T-shaped). Thick ribbed pseudoplacoid, T-shaped found only Macronematinae. The great diver...

While eggs are highly aggregated, they were laid at ...

This review of the status Australian caddisflies focuses on publications from 1982 to 2022. Information is provided new species described in that period, keys, descriptions both adults and larvae, distribution families genera states/regions Northern Territory. Australia’s caddisfly fauna now totals 27 families, 111 868 species, with 97.9% endemic Australia (only 19 are known outside Australia, ...

This paper describes the distribution for this rare species in Ozarks of Arkansas and Missouri thus expanding its known range region. The is considered vulnerable to anthropogenic stressors.

In addition to a list of valid names and synonyms, as provided by the Trichoptera World Checklist, access to the primary literature itself is essential for research in Trichoptera taxonomy and systematics. To improve access to bibliographic information, we established the Trichoptera Literature Database, http://www.trichopteralit.umn.edu, a bibliographic database of over 8,500 citations of lite...

Ecologists seek better understanding of why species interactions change across space and time in natural communities. In streams, species effects on resources and community structure may change as physical characteristics of the stream environment change along drainage networks. We examined spatial and seasonal effects of armored grazers using a small-scale exclusion experiment that was replica...
