Taenionema atlanticum Ricker & Ross, 1975

Notes

This species is commonly referred to as the Atlantic Willowfly ( Stark et al. 2012), and is known from Quebec and Newfoundland-Labrador southwestward mainly through the Appalachian Mountains to Tennessee and South Carolina ( Stewart 2000, DeWalt et al. 2024). Harper et al. (1991 a) reported a univoltine life cycle from a small Laurentian Highlands stream in Quebec. In New York, adults of T. atlanticum have been collected from late February to mid-July (Fig. 22 ), from elevations ranging from 25-609 m asl (Fig. 23 ). This species is widely distributed across the state and is commonly collected from small streams from the Appalachian Plateau east to the Adirondacks and surrounding lowlands, and south to the Lower Hudson Valley near the northern edge of New York City (Fig. 24 d ).
