Uhler's Water Bug (Lethocerus uhleri)
5-30-11

These guys are true bugs and are aquatic. There was a time when they were called "Electric Light Bugs" because they commonly come to light. They are also sometimes called "Toe Biters" and they can indeed pack a wallop for an unwary wader with their beak filled with painful fluids that break down their prey's tissues (which can include small fish and tadpoles.)
