Allocapnia pechumani Ross & Ricker 1964

Allocapnia pechumani Ross & Ricker, 1964 Notes This species commonly referred to as the St. Lawrence Snowfly (Stark et al. 2012), has been reported patchily from Quebec and New Brunswick southwest to Ohio (Ross and Ricker 1971, DeWalt et al. 2024). This species was named in honor of the late Dr. Verne Pechuman, a tabanid fly expert who conducted research at Cornell University. Although this species is widely distributed across much of the southern areas of the state, in northern areas it appears it is restricted to lower elevations of Level IV Ecoregions Champlain Lowlands (83 b), Ontario Lowlands (83 c), and Mohawk Valley (83 f) (Fig. 11 d) and often in association with A. maria. In New York, adult collections occur from early March through mid-April (Fig. 7) in small streams with elevations ranging from 32-577 m asl (Fig. 9).
