Allocapnia ohioensis Ross & Ricker, 1964

Notes

Allocapnia ohioensis is commonly known as the Ohio Snowfly ( Stark et al. 2012). The range of this species is similar to that of A. indianae , including disjunct New York populations ( Ross and Ricker 1971, DeWalt et al. 2024). This species has been previously reported from small, gravel bottom streams ( Ross and Ricker 1971). In New York, this species appears to be more uncommon than the previously mentioned sister species, A. indianae . A single record is available from New York, collected in late March 1960 (Fig. 7 ) from a low elevation (210 m asl) (Fig. 9 ) stream in Level IV Ecoregion 83 f Mohawk Valley (Fig. 11 c ).
