small winter stoneflies
Bolshecapnia is a genus of small winter stoneflies in the family Capniidae, first described by Ricker in 1965 as a subgenus of Capnia and later elevated to genus rank. The genus currently comprises four species distributed in western North America. Members of this genus are adapted to cold-water environments and exhibit the characteristic winter-emergence pattern typical of Capniidae.
