"The Colorado hairstreak graces the eighth nonmachinable butterfly USPS stamp for use on irregularly sized envelopes, such as square greeting cards, invitations or announcements. The stamp art is a highly stylized, simplified image of a Colorado hairstreak (Hypaurotis crysalus). Artist Tom Engeman created the stamp art. Art director Derry Noyes designed the stamp."

"The square format of the stamp was developed in collaboration with the greeting card industry specifically for oversized or square envelopes. These envelopes cannot pass through the automated Postal Service processing system and have to be hand-cancelled. The envelopes are charged a non-machineable surcharge even if they weigh less than 1 ounce. Greeting card envelopes printed with a silhouette of a butterfly indicate the need for additional postage — or the use of a butterfly stamp. Any nonmachineable envelope, like oddly-shaped or vertical envelopes, as well as lumpy envelopes, rigid envelopes and mail with clasps, ribbons and buttons may use this stamp." [USPS.com]
