swamp milkweed leaf beetle
This large ladybug looking beetle is feeding on my butterfly plant (Asciepias) here in south central Wisconsin (Dodge County). I included a ruler (using metric) for reference in size in the picture. Actually got 2–mating I imagine. From your page and other websites it would certainly appear to be Labidomera clivicollis or swamp milkweed leaf beetle. Feel free to use the image if it is useful to you.
