|scientific name Xestia maculata |
In Alberta adult have been collected in late July.
A medium-size moth (approximately 3 cm wingspan) strongly patterned grey and black diurnal moth. Forewings are black with light grey markings, producing a strongly patterned appearance. The basal and subterminal areas in particular are banded with pale grey, and the prominent round orbicular and the reniform spot are filled with the same pale color. The postmedian line is prominently dentate. Hindwings black with a light fringe. The strongly patterned appearance and lack of any brown color will separate it from other Alberta alpine noctuids.
Very poorly known. Adults are diurnal. In Alberta adult have been collected in late July. The larva and host plant(s) are unknown.

Xestia maculata occurs at high elevation in the mountains from southwestern YT south in the mountains in eastern BC and western AB to northern MT. It frequents open alpine habitats.
This little alpine moth is known from few sites in western Canada and Montana. However, its rarity is likely due more to the difficulty in accessing the habitat. In Alberta it was known only from the type locality (Lake Louise) until 2006, when it was found to be not uncommon in alpine areas of the Kakwa Wilderness area, north of Jasper National Park.
