It is found from British Columbia to California. The wingspan is 30-40 mm. Adults are on wing from August to October, with a few records from May to July. The larvae feed on the leaves of flowering trees and shrubs. A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. Moths form the majority of this order; there are thought to be 150,000 to 250,000 different species of moth (about ten times the number of species of butterfly), with thousands of species yet to be described.
