Plectrocnemia
tube maker caddisflies
Plectrocnemia is a genus of tube maker caddisflies in the family Polycentropodidae comprising more than 120 described species. Larvae are aquatic predators that construct silken capture nets to intercept prey. The genus has been extensively studied for its larval silk production, vibration-mediated predatory behavior, and population genetics. Species occur across Europe and into western Asia, with detailed biological information available for several well-studied species including P. conspersa and P. brevis.

Psychomyiidae
Net Tube Caddisflies, tube-making caddisflies, trumpet-net caddisflies
Psychomyiidae is a family of tube-making caddisflies (order Trichoptera) characterized by larvae that construct silken galleries or tubes on submerged surfaces. Adults are typically small with reduced wing venation, including absence of forewing fork I and shortened hindwing forks. The family is distinguished from similar Polycentropodidae by leg spur formula 2-4-4, short thyridial cell, and male genitalia with elongate preanal appendages and reduced tergum IX. Larvae possess separated submental sclerites, broad foretrochantin, and whip-like pupal mandible apices. The family contains approximately 10 extant genera and has a global distribution with notable diversity in the Oriental and Western Palearctic regions.

Pycnopsyche gentilis
caddisfly
Pycnopsyche gentilis is a northern caddisfly in the family Limnephilidae. Larvae are shredders that inhabit allochthonous organic materials in freshwater streams, where they feed on leaf litter colonized by aquatic fungi. The species is contemporaneous with congeneric P. luculenta, though larvae differ in case materials and habitat preferences. Adult males exhibit temporal partitioning of flight activity, with distinct peak arrival times at light sources when active on the same night as congeners.

Rhyacophila
caseless caddisflies
Rhyacophila is a large genus of caddisflies (Trichoptera) in the family Rhyacophilidae, comprising at least 640 described species. The genus is cosmopolitan in distribution, with significant diversity in Europe, Asia, and North America. Larvae are commonly known as 'caseless caddis' because they do not construct portable cases, instead using silk to anchor themselves to substrates in running water. The genus exhibits high endemism in certain regions, with multiple species restricted to specific mountain ranges or islands.
