Macoun's Arctic
Oeneis macounii
<< >>

General Description

By Nora Bryan

The Macoun’s Arctic can be found across Alberta except for the southern prairies. Unlike most of Alberta’s satyrid butterflies, this Arctic is at home in forests, especially pine forests in the mountains and northern part of the Province. Look for them sailing through the forest in June and July in odd-numbered years.

The upper wing surfaces are orangy brown with dark margins and there are one to four eye-spots with the larger ones having white pupils on the forewing. The hind wing has a single spot. The eyespots are repeated on the underwing surface, which is marked in dark browns and pale greys. The wingspan of this graceful flier is 45 to 65 mm (1 ¾ to 2 ½ in.).

The caterpillar has a black line on the back and black, white and tan lines on the sides. The head has six dark stripes. It probably eats grasses.
