These were determined to genus using Merritt, Cummins and Berg (2008) as well as Wiggin's "Larvae of the North American Caddisfly Genera" (1996). They were identified to species using Don Burdick's illustrations of Trichoptera. Mature male pupae were used to make the species determination.

The mature larvae were 3 - 3.5 long with the cases measuring about 4 mm in length. The pupal cases were about 4 - 4.5 mm long. The larvae were found on Cladophora algae in a fairly fast flow. The pupal cases were in aggregations on the rocks.
