Sandee Faust, a friend of this blog, passed along some photos of  classic Celery Farm summer sights -- a Green Frog (I think), a Spicebush Swallowtail (taken on Saturday's Butterfly Walk), and a Milkweed Bug (above).

As with the Monarchs that use the Common Milkweed as a host plant, the Milkweed Bugs taste terrible to any bird that tries to eat them.
