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.
