Allocapnia indianae Ricker 1952

Allocapnia indianae Ricker, 1952 Notes This species is commonly referred to as the Indiana Snowfly (Stark et al. 2012). Allocapnia indianae is known from the lower Ohio River valley region encompassing Kentucky, Indiana, Ohio, and West Virginia, plus a disjunct set of localities in New York (Ross and Ricker 1971, DeWalt et al. 2024). In New York, this species is known only from historical reports with the most recent collection in 1966. Ross and Freytag (1967) reviewed the current distribution and probable post-Pleistocene dispersal routes of this species and its closely related sister species A. ohioensis. In New York, adults have been collected from early March to early April (Fig. 7) from small streams at 117-577 m asl (Fig. 9). Verified reports are available from Level IV Ecoregions Catskill High Peaks (58 y), Glaciated Low Allegheny Plateau (60 a), Finger Lakes Uplands and Gorges (60 d), Ontario Lowlands (83 c), and Mohawk Valley (83 f) (Fig. 10 e).
