I have been taking pictures of butterflies

In the last several years I have gotten quite interested in Skippers and Butterflies. I am especially intrigued with their very close evolutionary relationships with the plants that females recognize and caterpillars will eat.

The butterfly on the top is a Horace's Skipper, in the middle is a Spicebush Swallowtail and on the bottom is a Common Woodnymph. The rest of my pictures are here.
