I photographed this Eastern Tiger Swallowtail on the side of the auto tour road located at the Sequoyah National Wildlife Refuge (Oklahoma).

The fore-wings of the male, which are yellow, have four “tiger stripes” in black.
Females are dimorphic and can be either yellow or black.
The dark morph is almost entirely black, whereas the yellow morph has a noticeable band of blue dots down the hind-wing, making it look more like the male.
