Giant Water Bug (in the genus Lethocerus, likely Lethocerus americanus): At up to about 3 inches in length, these water bugs really are giants. They are commonly called “toe biters”, because as a type of true bug (piercing / sucking mouth parts) they can deliver a painful poke. They generally live in stagnant, slow moving waters where they capture and consume other insects, small fish, frogs, and even snakes. Aside from finding them in the water, they are attracted to lights at night …which means, yes, they can fly. Photo by Matt Schaefer on 5/15/18 in Stevensville, MT.
