Which family is commonly known as Giant Water Bugs?

• A. Belostomatidae (Giant Water Bugs)
• B. Notonectidae (Backswimmers)
• C. Corixidae (Water Boatmen)
• D. Nepidae (Waterscorpions)

Answer: (A)

Giant water bugs refer to a group of large predatory aquatic true bugs that belong to the family Belostomatidae. These insects are notable for their substantial, broad bodies and powerful front legs that they use to grasp prey, allowing them to hunt underwater in freshwater habitats. A distinctive aspect of Belostomatidae biology is that the male often carries the eggs on its back until they hatch, illustrating a unique form of parental care. The other families mentioned are different in appearance and lifestyle: backswimmers are smaller and swim on their backs; water boatmen are also small with oar-like hind legs; waterscorpions are elongated and have a long siphon for breathing. Because the common name “giant water bugs” is specifically associated with Belostomatidae, this is the correct family.
