Abstract: Soyedina vallicularia (Wu, 1923) Notes This species is commonly referred to as the Valley foestfly (Stark et al. 2012). Soyedina vallicualaria is known in Canada from mainland Labrador and Nova Scotia west to Ontario and in the USA from Maine west to Wisconsin and Iowa and southwest to North Carolina and Tennessee (DeWalt et al. 2024, Grubbs and Baumann 2023). Mackay (1969) and Harper (1973 a) documented a univoltine-slow life cycle for S. vallicularia from streams from Quebec and southern Ontario, respectively. Adults were present in May and larval recruitment began in June indicating a direct hatching of the eggs. In New York, adults of this species were active from early March through late June (Fig. 18). Soyedina vallicularia was recorded from a wide range of elevations ranging from 47-582 m asl (Fig. 19). Although this species was collected frequently in the eastern half of the state (Fig. 21 c), we anticipate that it is more common in western New York.
