Podmosta macdunnoughi

Podmosta macdunnoughi (Ricker, 1947) Notes Podmosta macdunnoughi is commonly referred to as the Maritime Forestfly (Stark et al. 2012). This species has been reported from Newfoundland-Labrador and Quebec southwest to New York and with an adjunct distribution in Minnesota (DeWalt et al. 2024, Grubbs and Baumann 2023). Harper et al. (1993) found that P. macdunnoughi displayed a univoltine-fast life cycle in a Laurentian stream and suggested a summer egg diapause. Our limited collections of this species in New York have indicated adults are active from late April to early May (Fig. 18). Reported elevations in New York range from 505-520 m asl (Fig. 19) from only two sites in Level IV Ecoregion Central Adirondacks (58 ad) (Fig. 20 e), which is apparently at the southern limits of its range, since this species becomes increasingly more common further north in northeastern Canada (Harper 1990 b, Kondratieff and Baumann 1994).
