Posts: 356		Adults and larvae were identified using "What is Capnia umpqua? Frison (Plecoptera: Capniidae) distribution and variation of terminalia" by Baumann and Stuart.http://illiesia.speciesfile.org/papers/Illiesia05-05.pdf as well as "Larvae of Five Species of the Winter Stonefly Genus Capnia (Plecoptera: Capniidae) From California, U.S.A." by Stewart, Drake and Stark. http://illiesia.speciesfile.org/papers/Illiesia07-18.pdf

Larvae were found in shallow water 2-12 inches deep. They were found in riffle areas and crawled out on rocks to emerge. They were present from January through March.
