It's not an Earwig ...

At first glance a Rove Beetle can easily be mistaken for an earwig. This one wasn't inclined to co-operate and pose for me ... it never rested long enough to fold its wings under its elytra. Due to the beetle being in constant motion and windy conditions and this is the only picture that stayed in focus.

Based on the description in Peterson's Field Guide to the Beetles, and images on the Internet, this looks like Lathrobium sp.

For comparison here's an Earwig (Forficula sp.). The well developed forceps-like cerci on the ends of an earwig's abdomen are hard and ... speaking from experience here ... they can can deliver a good pinch.
