Colorado Hairstreak (Non-Machineable Surcharge for Square Envelopes) (Sheet of 20) First-Class Mail Forever Postage Stamps Holiday Celebrations Wedding Invitations Announcements Anniversary

These colorful square non-machineable surcharge colorado hairstreak stamps were developed in collaboration with the greeting card industry. Its uses are on irregular-size envelopes. Such as square greeting cards, RSVP envelopes often enclosed with wedding invitations, party invitations, thank-you notes, announcements, or any other irregularly sized correspondence. So the Colorado hairstreak butterfly graces the eighth non-machineable butterfly stamp. The stamp art was digitally created using images of preserved butterflies as a starting point. The result is a highly stylized, simplified image of a Colorado hairstreak rather than an exact replica. The shimmering purple Colorado hairstreak butterfly dwells in the forest canopy of that state and much of the Southwest. Never venturing far from its host plant, the Gambel oak, it feeds on tree sap and fallen raindrops. The Colorado hairstreak – Colorado’s official state insect – has slender, hair-like, hind-wing appendages that resemble antennae. Nearby, on the underside of the wings, are spots that look like eyes and the thin streaks that give the hairstreak its name. Pointing its abdomen upward with false antennae held high, the butterfly’s evolutionary decoys fool predators into attacking the false head on the wing. A hungry bird ends up with an unsatisfying beakful of the scaly wing. In autumn, after mating, the female lays her eggs. The plump, green caterpillar hatches in spring and feeds on tender new oak leaves. After metamorphosis, the Colorado hairstreak butterfly, with a wingspan of about 1 inch, darts in and out of the tree branches in quick, erratic flight. These envelopes cannot pass through the automated Postal processing system and have to be hand-canceled. They are charged a non-machineable surcharge even if they weigh less than one ounce. Greeting card envelopes printed with a silhouette of a butterfly indicate the need for the use of a butterfly stamp. Any non-machineable envelope, like oddly shaped or vertical envelopes, as well as lumpy envelopes, rigid envelopes, or mail with clasps, ribbons, or buttons, may use this stamp. Colorado Hairstreak stamps is available in sheets of twenty. The words “NON-MACHINEABLE SURCHARGE” on the stamp indicate its usage value. Nationally known artist Tom Engeman created the stamp art. Art director Derry Noyes designed the stamp.
