It is found from British Columbia south to Oregon and California. It was formerly known as a subspecies of Drasteria mirifica. 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.
