About Hemaris thetis Boisduval, 1855
Hemaris thetis, commonly known as the Rocky Mountain clearwing or California clearwing, is a moth belonging to the family Sphingidae. This species was first formally described by Jean Baptiste Boisduval in 1855. Its range extends from Colorado, New Mexico, Montana, Idaho, Wyoming, and Utah westward to California, and northward to British Columbia. This moth inhabits streamsides and meadows located in mountainous areas. It likely produces one generation per year, with adult moths active on the wing between May and August. Adult Hemaris thetis feed on nectar from a variety of flowers, including Arctostaphylos uva-ursi and plants from the Lupinus genus. The larvae of this species feed on plants from the Symphoricarpos genus.
