Gnats are a type of small flying insect that belong to the suborder Nematocera, which comprises various species of small flies. These insects have slender bodies, delicate wings, and long legs. Gnats are primarily found in humid environments, such as near bodies of water or damp areas, and serve important roles in ecosystems as pollinators and decomposers. While most gnats are harmless, some species can become pests, particularly when they gather in large swarms. Certain types of gnats, such as biting midges, can bite humans and other animals, causing discomfort and irritation. Gnats are attracted to moist conditions and are commonly found in outdoor locations, including gardens and forests.
