We typically only post current submissions, but we had to make an exception for Barb’s beautiful photo. This is a day-flying moth you can see out and about right now from southern British Columbia south to Oregon, northeastern Nevada, Utah, Colorado, and northern New Mexico. A “black and white” moth …you can certainly see where the common name stemmed from. Larvae feed on mountain bluebells (Mertensia spp.) in the borage family.
