As I have mentioned in previous posts, the millpond is dotted with the stumps of bald cypress trees that were logged years ago. Cypress stumps take a long time to decay so they provide wonderful little islands that are colonized by a variety of plants. It isn't unusual to find a dozen or more species of plants growing on any given stump.

This Eastern tiger swallowtail, Papilio glaucus, was nectaring on a button bush (Cephalanthis occidentalis) that is growing on such a stump out in the middle of the upper end of the pond.

Other butterflies seen yesterday: Spicebush swallowtail, Red-spotted purple, Red Admiral, Eastern tailed blue, and Pearl crescent.
