Abstract: Allocapnia granulata (Claassen, 1924) Notes Allocapnia granulata is commonly referred to as the Common Snowfly (Stark et al. 2012). This widespread, common species has been recorded from southern Manitoba east to Quebec and south to Texas and USA Gulf Coastal states (Ross and Ricker 1971, DeWalt et al. 2024) and occurs in a wide range of streams and river habitats with varying degrees of flow and turbidity. This species distribution extends into northern New York along the Lake Champlain (Myers et al. 2011) and St. Lawrence River drainages. Ross and Yamamoto (1967) and Ross and Ricker (1971) each provided thorough discussions of post-Pleistocene dispersal pathways. As in other members of this genus, Harper and Hynes (1970) and Finni and Chandler (1977) found that larvae of A. granulata undergo an apparent diapause during the summer. In New York, adults of this species were collected late-January through early April (Fig. 7). Allocapnia granulata was found at a wide range of elevations (7-529 m asl) in streams and rivers throughout the state (Fig. 9, Fig. 10 c).
