Euxoa murdocki Smith 1890

An uncommon species, at the extreme eastern edge of its range in western Alberta.

In Alberta there is a single record for late August.

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.

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.

Dry open montane pine and fir forest.

There is a single annual brood, which flies in late summer. Adults come to light.

Euxoa murdocki is a species of cutworm or dart moth in the family Noctuidae. It is found in North America.

The MONA or Hodges number for Euxoa murdocki is 10846.
