Rhyacophila acutiloba
Morse & Ross, 1971
Rhyacophila acutiloba is a of free-living caddisfly in the Rhyacophilidae, first described by Morse & Ross in 1971. As a member of the 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) .

Habitat
Lotic (flowing water) environments, including rivers and streams with rocky or gravel substrates. As a free-living caddisfly, larvae occupy the spaces between stones on the riverbed.
Distribution
North America; specifically recorded from Vermont, United States, and other parts of the Nearctic region.
Life Cycle
Complete with , larva, pupa, and stages. Larvae are aquatic and free-living (caseless), developing in flowing water before emerging as terrestrial adults.
Behavior
Larvae are free-living that actively move between substrates rather than remaining in fixed retreats; are and attracted to light.
Ecological Role
Larvae function as in freshwater benthic , contributing to dynamics in lotic .
