I have posted pictures of this bug. Found in shallow water (and released) chasing another smaller bug. It bit me.
This is the first time we have gotten a photo of an immature Giant Water Bug, or Toe-Biter. Adults have wings and are strong fliers. There are human encounters when they are attracted to lights, hence their other common name, Electric Light Bug.
