Belostomatidae

A belostomatid is any member of the Belostomatidae, a family of freshwater insects known as giant water bugs.

A large swimming cockroach with segmented sturdy legs and stag beetle-like pincer antennae is what the biggest bug looks like. A bug taxonomically is a member of the Belostomatidae insect family, of which South American water bugs (Lethocerus grandis, L. maximus) are the largest, with total measurements exceeding 3-1/2 inches (9 centimeters).

South American water bugs are the biggest bugs on Planet Earth. They may belong to either the species grandis or maximus within the Belostomatidae true bug family genus Lethocerus and will measure 3.5+ inches (9+ centimeters) in their native Latin American habitats.
