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 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 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.
