|scientific name Syngrapha alticola |
common name Alticola Looper Moth
Alpine and arctic tundra.
Adults have been collected in Alberta in late July and early August.
A fairly small (2.6-2.7 cm wingspan) moth with blackish-brown forewings and bright yellow hindwings. Forewings are dark chocolate or black-brown, paler along the postmedian line and in the anal angle. The stigma is an oblique elongated curved silver spot. Hindwings are bright yellow-orange, with a prominent black terminal band. The antennae are simple and both sexes are alike. It can be separated from the very similar S. ignea by its smaller size, the darker forewings, shorter stigma, more zigzag subterminal line and the lack of sclerotized setae on the foretibia. They can also be separated by genitalic characters. The other small yellow-winged Syngrapha species are restricted to lower elevations than alticola frequents.
The adults are diurnal.
A widespread species with secure habitat; no concerns.
