Author: (Walker, 1863)
forewing length 1.1 - 1.3 cm (1)
Adults - dark-grey patterned forewings and shining dirty-white hindwings. The forewings are a mixture of dark slate grey markings over a pale grey ground. The forewing markings may be quite variable but the antemedian and postmedian lines are usually well marked, sinuous and doubled. The reniform is a gray spot with some rusty brown scaling in the pupil. The hindwing is dirty white, shading to light grey-brown towards the margin (from E.H. Strickland Entomological Museum)
Larvae - pale green with long, fine hairs (E.H. Strickland Entomological Museum)
Pupa - powdery white and characteristically truncated at one end (E.H. Strickland Entomological Museum)
British Columbia east to Nova Scotia and south to eastern Washington, Colorado, Tennessee, and Pennsylvania (1)
Newfoundland west to Vancouver Island, north to Northwest Territories and south to the Gulf of Mexico (E.H. Strickland Entomological Museum)
Open deciduous woodland and shrub (E.H. Strickland Entomological Museum)
adults are on the wing in late summer and fall and again in spring, and apparently overwinter (E.H. Strickland Entomological Museum)
larval host is willow (1), sometimes poplar (E.H. Strickland Entomological Museum)
Life Cycle
The larvae form colonies in leaves tied together in a silk web, although individuals may be found as well. Adults are apparently only poorly attracted to light, and may be much commoner than light trap collections indicate (from E.H. Strickland Entomological Museum)
See Also
The similar Nycteola cinereana can be separated from frigidana by its slightly larger size, pale grey color and the black scaling along the lower base of the forewings. Frigidana is most likely to be overlooked as a "micro-lepidopteran". There are also a number of similar appearing species among the Tortricidae (from E.H. Strickland Entomological Museum)
