Eastern Tiger Swallowtail Papilio glaucus

The common yellow and black garden swallowtail. Fluctuates widely in numbers from year to year. Has a black form (see below) which only occurs in females and in Arkansas at about a 10 to 20 percent incidence. In the east this normal form is not confusable with any other current species. In the west there are several species with this base pattern. If the Appalachian Swallowtail is found here it is separable by size and by the width and color of the marginal spot line on the upper forewing. Nectar hogs. This one is shown on a blooming Liatris which is almost 100% guaranteed to contain some Swallowtails in summer.

Black form Tiger, which, as stated, are always females. Note the blue pattern is not the same shape as the Spicebush. In backlight the tiger stripes show.  Another is shown below.

Side view from Camp in July of the black form with the tiger pattern showing like window glass. Even the body is blackened as you see.

Holy Grail shot from Tom of the mating female Black form and the male normal form from Bell March 2012. Even more astounding is that the male seems to have some Appalachian characters. Though one of the guys who described the Appalachian Swallowtail, which is now known to be a distant genetic mixing of the Eastern Tiger and the Canadian Swallowtail, has said that some early emergent Easterns often have some forewing drift toward the Appy conformation. These are both Easterns. There is apparently a rare black female form in the Appy.
