Acroneuria lycorias ( Newman, 1839)

Notes

This species is commonly referred to as the Boreal Stone ( Stark et al. 2012). Aconeuria lycorias has been reported in Canada from the Maritime Provinces west to Saskatchewan and in the USA from Maine west to Iowa and North Dakota plus south to Tennessee and North Carolina, with a disjunct distribution in Florida ( Pescador et al. 2000, Stark 2004, DeWalt et al. 2024). Previous observations of this species have suggested a two to three year life cycle ( Harper and Magnin 1969, Hitchcock 1974, Peckarsky 1979, Barton 1980). Peckarsky (1979) documented this species from a wide range of stream sizes, with adult emergence dates ranging from mid-April to early August. In New York, this species has been collected from mid-May to late July (Fig. 35 d ) from elevations ranging from 49-569 m asl (Fig. 34 ). This species is common in streams and large rivers across the state (Fig. 35 d ).
