Swamp Milkweed Leaf Beetle
Found on a hibiscus in a container at a local car dealership.
First time I have noticed this beetle in my garden. On a leaf of American Beautyberry which is near several Milkweed Honeyvines. July 3, 2010
Just hatched and beginning to eat. This leaf is only 1 inch long, also is not swamp mw...they eat all of them!
