Water boatmen are sometimes confused with backswimmers, which are generally larger bugs that swim upside down and deliver a painful bite.

Um i don't think. I know they bite humans like a mosquito though.
Backswimmers swim on their backs. They have cream colored wings and a dark underbelly. They also bite. They are found at the bottom of a shallow pond, and close to some plants. Boatmen swim on their stomachs and don't bite. They are found on the surface of the water.
They are called Backswimmers or Water Boatmen, believe it. In Jamaica, I've seen them bigger than the palm of your hand.

Boatsman insects eat aquatic plants, algae, and a few aquatic larva of other species. Backswimmers which look very similar, are predators and have a mean bite.
What are backswimmers adaptations
Gangs of Pond Skaters eat backswimmers although I dont know if they attack live creatures or just dispose of corpses.

Under their wings is where backswimmers [Notonectidae family] store their air. They need it for the deep dives by which they escape many predators. But when they run out of air, they must be able to get back to the surface quickly.
