On March 9, 2021, in Estes Park, CO, the United States Postal Service® will issue the Colorado Hairstreak stamp (Non-denominated priced at the Non-machineable Surcharge rate) in one design, in a pressure-sensitive adhesive (PSA) pane of 20 stamps (Item 121200). This stamp will go on sale nationwide March 9, 2021, and must not be sold or canceled before the first-day-of-issue.

The Colorado hairstreak graces the eighth non-machineable butterfly stamp for use on irregularly-sized envelopes, such as square greeting cards, invitations, or announcements. The stamp art was created digitally using images of preserved butterflies as a starting point. The result is a highly-stylized, simplified image of a Colorado hairstreak (Hypaurotis crysalus) rather than an exact replica. The Colorado hairstreak, that state’s official insect, is not attracted to flowers. The small, shimmering, purple butterfly perches in oak trees in the Southwest, sipping sap and raindrops. Tom Engeman created the stamp art. Art director Derry Noyes designed the stamp.

The Colorado hairstreak (Hypaurotis crysalus) is a montane butterfly native to oak scrubland in the southwestern United States and northern Mexico. It was designated the state insect of Colorado in 1996. It is the only species in the genus Hypaurotis.

The upperside of the Colorado hairstreak’s wings is dark purple with a broad black or dark border. Each wing has orange spots at the lower outer edge, and each hindwing has a thin hairlike tail. The lower side of the wings is pale to dark gray with white and dark markings, an orange patch on the margin of each forewing, and an orange spot with a black center on the hindwing near the tail. It has a wingspan of 3.1–3.8 cm (1.2–1.5 in).

This species depends upon the Gambel oak (Quercus gambelii), which is both the favorite roost of adults and usual food source for caterpillars. Eggs are laid singly in late summer on twigs of Gambel oaks or another oak species. The caterpillars emerge in the spring and eat young leaves. Adults feed on tree sap and probably honeydew secreted by other insects rather than on flowers. The species has one flight, usually from mid-June to August. It is found mainly in Utah, Colorado, Arizona, and New Mexico, the Colorado Plateau states, although it can also be found in small portions of Nevada, Wyoming, and Durango, Mexico.
