Since the larvae of Cotinis have such a unique way of crawling (on their back, caterpillar-style), I thought I'd add a sequence showing this. It is pretty funny to watch; when the grub is first disturbed, it curls up in the normal scarab style, but then flips over on its back and starts creeping along. If you turn it back to right-side up, it won't continue until it has rolled onto its back again. My dog once brought one in the house and lay in the middle of the floor watching this "toy" crawl across the carpet. When it would get too far away, she'd gently pick it up in her mouth and move it back!
