Pipevine.jpg (151109 bytes)If you ever see a Pipevine Swallowtail in your garden, you definitely will notice it.  They have the most beautiful blue iridescent hindwing. you will see in North America.  It really is an attention-getter.  It's also been called the Blue Swallowtail because of this blue iridescence.  Wing span is 2 3/4- 3 3/8 inches.  The underside of the hind wing has one row of seven orange spots in an iridescent blue field.  It's easy to distinguish from the Spicebush and Black Swallowtails if you remember that the Spicebush and Black have two rows of orange spots.  This foul-tasting butterfly is mimicked by six other butterflies in the eastern US, including four that live in Florida (Spicebush Swallowtail, the black form of the Eastern Tiger Swallowtail, the female Black Swallowtail, and the Red-spotted Purple).PipevineTop.jpg (106042 bytes)

In earlier times this species seems to have been more common in the Northeast, perhaps because ornamental pipevines were common garden plants in Victorian times.  The growth of butterfly gardening may bring them back!!!  This has caused their range to expand.

As you can see from my pictures, they are not easy to photograph.  The wings are in constant motion, so you can't get a 'still' shot.  The photographer who took the first pic at the top is better than I am!  And luckier ;-)
