I saw this beauty enjoying the Joe-Pye Weed over the weekend.
According to Wikipedia, the Eastern Tiger Swallowtail
adult males are yellow, with four black “tiger stripes” on each fore wing. The trailing edges of the fore and hind wings are black which is broken with yellow spots. On the medial margin of the hind wing next to the abdomen there are small red and blue spots.
There are two morphs of adult females, a yellow and a dark one. The yellow morph is similar to the male, except that the hind wings have an area of blue between the black margin and the main yellow area. In the dark morph, most of the yellow areas are replaced with a dark gray to a black. A shadow of the “tiger stripes” can still be seen on the dark females. The dark form is more common in the Southern portions of the range.
As you can see in the next photo, the blue is present on the hind wings, so this is a female.
There have been a number of Monarchs flying around as well and the chipmunk has started to hang around word must be getting out that our yard is becoming a good wildlife hangout.
