|scientific name Hemileuca hera |
common name Sagebrush Sheepmoth
Look for in the prairie region where sagebrush (Artemesia cana) is common.
The single AB record is from mid-August. Dates from Montana suggest peak activity is in early August
A relatively large moth, easily recognized by the black pattern on the white background. The only other species similar to this in Alberta is H. eglanterina, which has a pink and yellow ground colour, not white.
Not known for AB; may have a two-year life cycle, overwintering first as an egg, then as a pupa. These moths are active during the day and are not attracted to light.
More survey work is needed to determine this species' status in the province.
Larvae feed on Sagebrush (Artemisia tridentata, A. filifolia) in the southern U.S. Likely Artemisia cana in AB, as this is the only Sagebrush species found on the prairie.
There is only one record of this species for Alberta, from Dinosaur Provincial Park. It almost certainly occurs in the southeast corner of the province, because it is known from Govenlock, SK near the AB/SK border. Ranges from southern SK west to B.C., south to Arizona and New Mexico.
