The Family Nepidae, commonly known as the water scorpion, belongs to the insect order Hemiptera. These aquatic insects possess a long, slender body with raptorial front legs, which they use to catch their prey. While the term "water scorpion" is most commonly used to refer to these insects, there are several other synonyms for the Family Nepidae. These include the lesser-known terms "water stick insect," "lake scorpion," and "needle bug." Regardless of the name used, the Nepidae family plays an important role in freshwater ecosystems as both predator and prey, contributing to the delicate balance of aquatic life.
