It was described by Beutenmüller in 1900. It is found from Montana, south to Arizona and east to Kansas.Adults are on wing from June to August. The larvae feed on the roots of Amsinckia species and Lithospermum incisum. 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.
