Oligia mactata Guenée 1852

A common widespread species; no concerns.

Adults in Alberta August and early September.

Nova Scotia to British Columbia, south in the mountains east and west. In Alberta found throughout the grasslands and parklands region, as well as in the lower foothills and southern boreal forest.

A medium-sized (3.0-3.5 cm. wingspan) mottled dark brown-black or black moth. There is a broad diffuse black streak from the base through the fold, obscured in darker specimens. The normal lines and spots are outlined or filled with lighter scales and so stand out, in particular the large reniform and a larger area along the lower half of the wing between the postmedian and subterminal lines. The outer edge of the subterminal line also has a series of small pale wedges between the veins. Hindwings dark fuscous, with an indistinct discal lunule and a thin median band and pale, lightly checkered fringe. Antennae simple. Sexes alike.

Wooded areas.

Poorly known. There is a single brood each year, and the adults are nocturnal and come to light. The adults fly in late summer so the wintering stage must be the egg or early instar larvae.

No Alberta data; elsewhere reported to use Pedicularis canadensis, Galium, Vaccinium sp., etc. (Handfield, 1999).
