scientific name    Oligia rampartensis    

Dry wooded foothills and montane; riparian woodland in the Milk River valley.

Adults have been collected in Alberta in late July and early September.

A robust medium-size (3.2-3.5 cm wingspan) noctuid moth. The forewings are a beautiful mix of purple, maroon, orange, and pale yellow, changing subtly with the light angle. The round orbicular and oblong-rectangular reniform spots are pale yellow. The terminal areas are mostly yellow-buff, with a very fine, scalloped dark terminal line. The hingwings are white, overlaid with pink scales on the outer half. The head and thorax are solid creamy or pinkish buff. The closely related and very similar O. violacea occurs in BC; it has white hindwings without pink, a central orange-red tuft on the thorax and differences in the genitalia. The much smaller O. egens is dark rusty-orange with dark hindwings. Rampartensis is one of the most attractive noctuids, and is unlikely to be mistaken for anything else in Alberta.

life history
Poorly known. Adults are nocturnal and come to light. There is a single brood, which flies in late summer.

A rarely collected moth in Alberta, but no obvious reasons for concerns.
