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 View Figure 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 View Figure 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 View Figure 28 e ).
