|scientific name Idia lubricalis |
common name Glossy Black Idia
Dry shrubby and wooded areas; badlands shrub.
Adults are on the wing in Alberta in July and August.
A small (2.4-3.2 cm. wingspan) dull blackish brown with a glossy sheen. Both the forewings and the hindwings are crossed by a series of ill-defined jagged whitish lines. The hindwings are only slightly paler brown than the forewings, and are crossed by the same pale lines. The much larger, paler and broader-winged Idia occidentalis was until recently treated as a subspecies of lubricalis.
Adults come to both lights and sugar baits.
Uncommon but widespread; no concerns.
Like other members of the genus, they feed on fungi and decaying plant material rather than on living vascular plant tissue.
Across southern Canada, west across central Saskatchewan and Alberta to southwestern BC, south.In Alberta, lubricalis has been collected in dry habitats south of the boreal forest, south to Scandia and Dinosaur Provincial Park.
