Perlinella drymo

Perlinella drymo (Newman, 1839) Notes This species is commonly referred to as the Striped Stone (Stark et al. 2012). Perlinella drymo is distributed broadly across much of the eastern half of North America, with records from Quebec and Nova Scotia west to Minnesota, southwest to Texas, and south to Florida (Kondratieff et al. 1988, Stark 2004, DeWalt et al. 2024). The life history of this species remains unstudied, but Stewart and Stark (2002) suggested that larvae of this genus probably spend a large portion of their life cycle in the hyporheic zone. In New York, adults have been collected between early May through late June (Fig. 33) from low elevations at 32-241 m asl (Fig. 34). We found populations along wave-swept shorelines of large lakes and seasonally inundated floodplains of large rivers in Level IV Ecoregions Eastern Adirondack Foothills (58 ac), Finger Lakes Uplands and Gorges (60 d), Champlain Lowlands (83 b), Upper St. Lawrence Valley (83 e), and Mohawk Valley (83 f) (Fig. 37 e).
