|scientific name Euxoa murdocki |
Dry open montane pine and fir forest.
In Alberta there is a single record for late August.
E. murdocki belongs to the detersa group of the subgenus Euxoa. It is a relatively small Euxoa species (wingspan 2.8-3.1 cm.). The forewing is rusty orange, crossed by a wide blue-grey median band, which incorporates the large blue-grey orbicular and reniform spots. The antemedian and postmedian lines are black, bordered by a mirror image in light brown. There is a dark grey-brown terminal band. Hindwings are light sooty-buff. The rusty-orange basal and subterminal area with the grey median area is a unique pattern among the Euxoa.
There is a single annual brood, which flies in late summer. Adults come to light.
An uncommon species, at the extreme eastern edge of its range in western Alberta.
No information available.
A western species, occurring mainly west of the continental divide, from western Montana and western Colorado west to southern California, and north to the southern interior of British Columbia. A specimen from Banff is the only record for Alberta, and is apparently the only specimen known from east of the continental divide.
