The crowned slug caterpillar. Stinging setae line the craned slug's perimeter, decorating its flattened, green body. Later in star's may also be marked with colorful red and yellow spots along the caterpillar's back. It is found in woodlands, from Florida to Mississippi, north all the way to Minnesota, southern Ontario, and Massachusetts. It feeds mostly on oak, but also elm, hickory and maple. Photo by Arddu.
