Rhyacophilidae
Guides
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.

Himalopsyche phryganea is a free-living caddisfly species in the family Rhyacophilidae, first described by Ross in 1941. Molecular phylogenetic studies have established it as the sole member of the phryganea species group within the genus. The species is known from North America, though the genus Himalopsyche is predominantly distributed in alpine to montane regions of Central and East Asia.
Rhyacophila acutiloba
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 angelita
Rhyacophila angelita is a species of free-living caddisfly described by Banks in 1911. It belongs to the family Rhyacophilidae, a group characterized by predatory larvae that do not construct portable cases. The species is known from North America.
Rhyacophila carpenteri
Rhyacophila carpenteri is a free-living caddisfly species in the family Rhyacophilidae, described by Milne in 1936. It is found in North America. As a member of the genus Rhyacophila, it belongs to a group commonly known as 'caseless caddis' that do not construct protective cases during their larval stage.
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.
Rhyacophila oreta
Rhyacophila oreta is a species of caseless caddisfly in the family Rhyacophilidae, described by Ross in 1941. It belongs to a genus whose larvae are free-living predators in freshwater habitats, constructing no protective cases. The species is known from North America in the Nearctic region. As with other Rhyacophila species, the larvae are aquatic and the adults are terrestrial, short-lived, and primarily reproductive in function.
