|scientific name Dysstroma suspectata |
Associated with boggy forests in the mountain and northern boreal regions.
Adults have been collected in Alberta from mid July through mid August.
This 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).
Data on the North American populations of this holarctic species are lacking.
Not of concern.
Larvae feed on Populus (Handfield 1999), and likely other plants.
A northern species, although it has not been recorded from the YT (Lafontaine & Wood 1997). Known from NWT, east to NS and NH (Ferguson 1954), apparently reaching its southern limit in the west in Alberta.
