It looks like an early instar stink bug. Between hatching from an egg and final adult sexual maturity, stnk bugs go through a number of developmental stages called instars. At the end of a given instar, they molt, shedding their previous exoskelton. The one in your picture looks like a second or even first instar animal. See the link below--

I found this bug on me and I was wondering what it was. Thanks!
