Amphinemura wui (Claassen, 1936)

Notes

Amphinemura wui is commonly known as the Spiked Forestfly ( Stark et al. 2012). The distribution of this common Appalachian species extends from Quebec and the Canadian Maritime Provinces south to Georgia and Alabama ( DeWalt et al. 2024). Previous studies in Quebec have suggested a complex univoltine life cycle for this species with two larval cohorts, indicated by an extended emergence period of the adults ( Harper and Pilon 1970, Harper 1990 b). In New York, this species has been commonly reported from eastern portions of the state including Level III Ecoregions Northeastern Highlands (58), Northeastern Coastal Lowlands (59), Northern Allegheny Plateau (60), and Eastern Great Lakes Lowlands (83) (Fig. 17 d ). Collection dates of this species from New York also indicate an extended emergence period, with adult collections from mid-May through late September (Fig. 18 ). This species occupies a wide range of elevations from 65-866 m asl (Fig. 19 ).
