Allocapnia recta

Allocapnia recta (Claassen, 1924) Notes This widespread species commonly referred to as the Eastern Snowfly (Stark et al. 2012), ranges from southeastern Canada, southwest to Louisiana and west to Illinois and Wisconsin (Ross and Ricker 1971, DeWalt et al. 2024). This is a common member of the genus and is found in both perennial and intermittent spring-fed streams (Hitchcock 1974). Grubbs et al. (2006) studied the life history of A. recta in a central Kentucky karst headwater stream and found that larvae entered an apparent diapause throughout the summer months. In New York, adults are active from early November through mid-April (Fig. 7). This species was collected in New York from small streams at elevations ranging from 33-447 m asl (Fig. 9). This species is distributed across the state but is primarily restricted in northern regions to low elevation valleys surrounding mountainous areas of the Adirondacks, Catskills, and Tug Hill Plateau (Fig. 11 f).
