Capnura manitoba

Capnura manitoba (Claassen, 1924) Notes Capnura manitoba is commonly referred to as the Manitoba Snowfly (Stark et al. 2012). This species ranges in Canada from Quebec and New Brunswick south to the USA from Maine west to Wisconsin (Nelson and Baumann 1987, DeWalt et al. 2024). Harper and Hynes (1972) suggested that larvae of C. manitoba undergo a summer diapause similar to A. pygmaea. Little is known about the habitat and microdistribution of the larvae of this species (Stewart and Stark 2002). In New York, adults were collected from mid-February through early June (Fig. 7) at 157-602 m asl (Fig. 9) from small, pristine spring-fed streams in Level IV Ecoregions Acid Sensitive Adirondacks (58 aa), Northern and Western Adirondack Foothills (58 ab), Eastern Adirondack Foothills (58 ac), Central Adirondacks (58 ad), Glaciated Reading Prong / Hudson Highlands (58 i), Champlain Lowlands (83 b), and Mohawk Valley (83 f) (Fig. 12 d).
