2013 66¢ Spicebush Swallowtail Butterfly Imperforate
Butterfly Series
As the target of many predators, the spicebush swallowtail uses mimicry to protect itself. By imitating other creatures or objects, it wards off birds, spiders, and other preying hunters. The young swallowtail most often begins its life on the leaves of its namesake plant, the spicebush. Scientists have discovered the adult female butterfly has a chemical compound that compels her to lay eggs on this plant, though others are occasionally used.
When the young larva hatches, it eats part of the leaf and exudes silk. This causes the leaf to fold over the larva, creating a shelter. The young larva is generally a brownish color, similar to bird droppings – its first stage of mimicry to ward off predators. When the larva grows older, it turns a yellow-green color and has two large black spots with white dots on its head – resembling a snake. It also has a red y-shaped organ it exposes when attacked, that mimics a snake’s tongue.
The swallowtail’s mimicry continues as an adult, as it resembles a pipevine swallowtail, which is a foul-tasting butterfly many predators know to avoid. The spicebush swallowtail flies close to the ground, unlike most butterflies. It also flutters its wings while it feeds, while other species stop to feed. These traits help give a unique identity to a species that spends much of its life mimicking other creatures.
Tom Engeman of Delaware used computer software to design the Spicebush Swallowtail, as well as the other butterfly stamps in the series so far. Engeman has designed a number of other U.S. stamps and postal stationary, including the entire 60-stamp Flags of Our Nation series and the Liberty Bell Forever stamp.
Value: 66¢ 2-ounce first-class letter rate and 1-ounce nonmachinable first-class letter rate

The Spicebush Swallowtail stamp is the third in a series Butterfly stamps issued for use on square envelopes such as greeting cards weighing up to one ounce. Many envelopes now have a silhouette of a butterfly in the upper-right corner to indicate extra postage is needed.
Scarce Modern Imperforates
The modern imperforate stamps are one of the hottest stories around. In 2012, the U.S. Postal Service released some issues as press sheets. The sheets with die cut perforations were issued in limited quantities.
To the surprise of many collectors, officials then issued a small number of press sheets without perforations. The uncut sheets were only available in Kansas City, Missouri, yet most sold out immediately. In an instant, the imperforate stamp sheets became modern rarities. For example, only 75,000 Baseball All-Star se-tenant sheets were issued compared to 118,000 Bugs Bunny sheets with the 10th stamp imperforate.
In a controversial move, the editors of Scott Catalogue announced they would not list or give numbers to these stamps because they did not fit Scott guidelines. This decision was strongly debated since the imperforate stamps are valid for postage. They eventually decided to give the stamps minor numbers and have continued issuing imperforates in the years since.
Because they were issued in such limited quantities, these scarce modern imperforates can be difficult to find. Luckily Mystic purchased a small number of each imperforate stamp issued so you can add these modern rarities to your collection. Be one of the lucky few – order today.
