Alloperla petasata Surdick 2004

Alloperla petasata Surdick, 2004 Notes Alloperla petasata is commonly referred to as the Woodlands Sallfly (Stark et al. 2012). This is a common species known from Labrador east to Ontario and southwest to Tennessee and Georgia (Surdick 2004, DeWalt et al. 2024). Previously, this species was known as A. caudata Frison, 1934 (Surdick 2004), a smaller species of the unglaciated states west of New York. Fishbeck (1987) reported peak emergence in mid-June from Gray’s Run in Northeastern Ohio. In New York, adults of A. petasata have been collected frequently from late May to mid-August (Fig. 26), often in association with A. atlantica and A. chloris. Documented occurrences of A. petasata from the study area range in elevation from 111-720 m asl (Fig. 27) from numerous streams and rivers in Level III Ecoregions Northeast Highlands (58), Northern Allegheny Plateau (60), and Eastern Great Lakes Lowlands (83) (Fig. 28 e).
