ground beetle

5868   Hi, I live in Washington state and found this bug at night under some maple leaves outside. I have never seen anything like this. Thank you.

This is a larva of a ground beetle (Coleoptera: Carabidae); see http://tinyurl.com/hc9ts8x for an image of an adult along with a larva. These all are general predators on other terrestrial arthropods, mainly other insects. Your specimen is one of the fattest examples that I’ve ever seen!
