The species of gnats belong to the families of Mycetophilidae, Anisopodidae and Sciaridae. Unlike fruit flies, there’s a lot of variation in diet and habitat needs between different gnat types.

They have a slender body with long legs which makes them look similar to mosquitoes. Adults can grow up to ¾-inches long.
