Toe-biters, scientifically known as Belostomatidae, are large aquatic insects commonly found in freshwater habitats like ponds and streams. They are named for their painful bite, which can feel like a sharp sting. These insects are typically brown or green and can grow up to 4 inches long. Toe-biters are predatory and feed on fish, amphibians, and other small aquatic creatures. They use their strong front legs to capture prey and have a unique breathing system that allows them to stay submerged for long periods. Despite their intimidating appearance, they play an important role in their ecosystems.
