What is a Water Bug?
A water bug is a type of aquatic insect. Often people call a common house pest a water bug, but that bug is actually a large type of cockroach. Bugs in this category can belong to several different families, including the Notonectidae, Nepidae and Belostomatidae families. Water bugs are scientifically classified as belonging to the Hemiptera order. Boatmen (Corixade), water scorpions (Nepidae) and backswimmers (Notonectidae) are some of the most well-known waterbugs. Sometimes, however, the name water bug is used to refer to giant water bugs (Belostomatidae) to the exclusion of these other types of bugs.
