Pat:

We collected a black beetle that is 3.2 cm long and 1.5 cm in maxium width. It is lens shaped in the top view and its ends are pointed, especially the rear. It was found on a tennis court in Pleasant Hill, Ca.

You must live by water because your little beetle friend is a predaceous diving beetle. They eat other aquatic insects and even small fish. What’s cool about these guys is that in order to breath they form an air bubble at their rear underneath the tips of their wings (elytra).

Cool find
