Colorful Beetle
I found this colorful beetle, which at first glance appears to be a super laybird beetle, on swamp milkweed in a garden in Milwaukee, WI on July 19, 2008. Two views.

Hi Bob,
You actually had your answer in your question. You knew it was a beetle and you knew it was on swamp milkweed, and it is a Swamp Milkweed Beetle, Labidomera clivicollis.
