Himalopsyche
Himalopsyche is a genus of free-living caddisflies in the family Rhyacophilidae, containing more than 40 described species. The genus is primarily distributed in alpine to montane environments across Central and East Asia and North America, with its greatest diversity concentrated in the Himalayas and surrounding mountain ranges. Species within the genus have been divided into five morphological groups: kuldschensis, lepcha, navasi, phryganea, and tibetana. The genus has served as a model system for studying mountain biodiversity, gene flow, and the mountain-geobiodiversity hypothesis due to its endemic distribution in geologically dynamic regions.

Rhyacophila acutiloba is a species of free-living caddisfly in the family Rhyacophilidae, first described by Morse & Ross in 1971. As a member of the genus Rhyacophila, it belongs to a group commonly known as "caseless caddis" or "free-living caddisflies" whose larvae do not construct portable cases. The species is known from North America, with records from Vermont and other parts of the Nearctic region. Like other rhyacophilids, it is associated with lotic (flowing water) habitats.
Rhyacophila grandis
Rhyacophila grandis is a species of free-living caddisfly in the family Rhyacophilidae, first described by Banks in 1911. Unlike many caddisflies, it does not construct portable cases as larvae. The species is documented from North America, though specific details about its biology and ecology remain limited in the available literature.
Rhyacophila manistee
Rhyacophila manistee is a species of free-living caddisfly described by Ross in 1938. As a member of the family Rhyacophilidae, its larvae are caseless, constructing silk retreats rather than portable cases. The species is known from North America, though specific details about its ecology and distribution remain limited.
