My wife found this swamp milkweed leaf beetle (Labidomera clivicollis) while weeding in the garden (which, at the moment, is basically just weeds). True to form, it was perched on a milkweed leaf. We planted the milkweeds a couple of years ago to attract monarchs. No monarchs yet, but we have found all sorts of other creatures on them. Milkweed plants, we have found, also have a penchant for spreading willy-nilly in a garden.
