Paragnetina media

Paragnetina media (Walker, 1852) Notes Paragnetina media is commonly known as the Embossed Stone (Stark et al. 2012). The range of this widespread species extends from New Brunswick northwest to the Northwest Territories, west to Minnesota and Iowa, and southwest to Arkansas (Hart et al. 2025, Stark 2004, DeWalt et al. 2024). A two-year life cycle has been reported for P. media in Michigan (Heilman and Knight 1970) and Kentucky (Tarter and Krumholz 1971). Harper (1973 b) reported a three-year life cycle and parthenogenetic females in southern Ontario. In New York, adults have been collected between early June and mid-July (Fig. 33) from larger streams and rivers at elevations ranging from 50-658 m asl (Fig. 34) and is broadly distributed across much of the state (Fig. 37 b).
