|scientific name Clostera strigosa |
common name Striped Chocolate-tip
Poplar and mixedwood forest.
Adults are on the wing in Alberta from late May to early July.
A medium-size (2.5-3.0 cm wingspan) stubby-winged dusky brown moth with lighter oblique lines crossing the forewings and a straw yellow blotch near the apex. Hindwings the same color as forewings, but unmarked. The antennae are bipectinate and both sexes are similar. Similar to other Clostera species, in particular C. apicalis, but with a more mottled appearance. The pale yellow or gold patch near the apex separates strigosa from other Clostera species.
There is one annual brood, which emerges in late spring. The adults are nocturnal and come to light. Unlike other members of the genus, strigosa is uncommon and usually only one or two specimens are collected in a season.
Although suitable habitat and hosts are abundant, this moth appears to be uncommon in Alberta.
No Alberta data. Elsewhere reported to feed on aspen poplar (Populus tremuloides) (Forbes, 1948).
From Nova Scotia west across southern Canada to extreme southeastern BC (Wasa), south to Maine and New York. In Alberta found in the southern boreal mixedwood forest and aspen parklands.
