Species Details
Dysstroma suspectata
University of Alberta E.H. Strickland Entomological Museum Read more about this collection »
SeasonalityAdults have been collected in Alberta from mid July through mid August.
IdentificationThis group of Dysstroma, consisting of D. citrata, suspectata, walkerata, and truncata, forms a complex of species which are often difficult to distinguish without resorting to genitalic differences. D. suspectata can usually be recognized by its dark brown-grey hindwing and forewing (particularly the underside), which is much darker than other Dysstroma. It occurs only in boggy forest habitats, such as black spruce bogs. McDunnough (1946) illustrates the male genitalia (as D. infuscata).
Our populations belong to subspecies mackieata (Cass. & Swett).
