The Postal Service will float the eighth stamp in its butterfly series, Colorado Hairstreak, on March 9.

Colorado’s state insect lives, feeds and reproduces on the scrub oaks of the southwestern United States and northern Mexico. A hairstreak may spend its entire life cycle within a few yards of its birth.

The 75-cent stamps in the butterfly series were designed in collaboration with the greeting card industry for use on unusually shaped cards and letters that require additional postage. The words “non-machinable surcharge” are printed on the front and, like Forever stamps, they will always retain their class-of-mail value.

Artist Tom Engeman provided the bright, simplified purple-and-orange imagery; Derry Noyes, a USPS art director, was the stamp’s designer.

The Postal Service will dedicate the stamp March 9 at 11:30 a.m. EST in a virtual ceremony that will stream on the organization’s Facebook and Twitter pages.

The stamp will be available at Post Offices and usps.com.
