Belostomatidae is a family of large aquatic insects commonly known as "toe-biters." They are found in freshwater habitats like ponds, lakes, and slow-moving rivers. These insects are characterized by their flattened bodies and long, powerful legs, which they use for swimming and capturing prey. Belostomatidae are predatory and primarily feed on other insects, small fish, and amphibians. They have a unique method of hunting, using their strong forelegs to grasp their prey. Some species can deliver a painful bite to humans, hence their nickname. They play an important role in their ecosystems as both predators and prey.
