Notonecta glauca latin

They are not related to Notonecta glauca, the water boatman or back swimmer.

Notonecta glauca is a species of backswimmer.

They are similar to Notonecta glauca, the water boatman or back swimmer by appearance, although these lesser waterboatman are herbivores and swim on their fronts.

The Common Backswimmer is Notonecta glauca, widespread in the United Kingdom (where they are known as water boatmen) and Europe.

The rostrum can also be used to sting in defence; some, like the common backswimmer (Notonecta glauca) of the Notonectidae can easily pierce the skin of humans and deliver a wound often more painful than a bee's sting.

Members of the Corixidae are known in the United States as water boatmen, a term that is sometimes used in the United Kingdom for Notonecta glauca, a bug of a different family, Notonectidae, and Corixa punctata is the "lesser water boatman".
