The Eastern Tiger Swallowtail butterfly(Papilio glaucus) is one of the most common and easily identified butterflies. With the bright yellow color and distinctive stripes, it even has an easy-to-remember name.

This is also a butterfly where it is easy to determine the male and female.

The female has a row of blue on the open lower wings. There is also a dark form of the female that has no yellow.

The male lacks the row of blue and just has the yellow and black coloration.

Here are a couple of other shots.
