Common NameDull Flatbody Moth
SeasonalityCan be found flying from early April through to the end of May (Hodges 1974) with one generation occurring each year.
IdentificationSemioscopis inornata has bluish-gray forewings that distinguish it from other brown winged Semioscopis species (Hodges 1974). The forewing of some specimens may have darker or yellow-brown scales (Hodges 1974). A black, convex band in forewing discal cell region may or may not be present (Hodges 1974). Typically, two black dots are evident in the basal forewing region and flanked posteriorly by a faint, curved line (Hodges 1974). Forewing length is between 10.5 to 15.0 mm (Hodges 1974). Female inornata have a distinctively long ductus bursae, while the male sacculus is approximately parallel to the valva costal margin (Hodges 1974).

Female inornata have a distinctively long ductus bursae, while the male sacculus is approximately parallel to the valva costal margin (Hodges 1974).
Life History
Larvae are leafrollers and occur in June and July (Hodges 1974). Although not reported pupation likely occurs in the ground and is the overwintering life stage (Hodges 1974).
Conservation
Due to the widespread distribution of this species, conservation is likely not of concern.
Diet Info
Larvae are known to feed on trembling aspen (Populus tremuloides), largetooth apsen (Populus grandidentata), willows (Salix spp.) and balsam poplar (Populus balsamifera) (Prentice 1965).
Range
Occurs throughout Canada and northern United States (approximately following the 40° N parallel) (Hodges 1974).
