Allocapnia zola Ricker, 1952

Notes

This species is commonly known as the Ash Snowfly ( Stark et al. 2012), occurs in a diagonal band flanking the western edge of the Appalachian Mountains from New Brunswick southwest to Tennessee ( Ross and Ricker 1971, DeWalt et al. 2024). Ross and Ricker (1971) reported this species from medium-sized streams with rocky substrates, with collection dates extending from late December to early April. In New York, this species is known from only one historical collection event on April 13, 1937 (Fig. 7 ) from a stream at 253 m asl (Fig. 9 ) from Level IV Ecoregion Erie / Ontario Lake Plain (83 a) in western New York (Fig. 12 c ). Further collecting in western New York should reveal additional populations.
