However, adult fungus gnats have long, slender bodies and that are mosquito-like in appearance, but without the long proboscis. Many fungus gnat species will have smoke-colored wings that feature a Y-shaped vein. The average adult fungus gnat grows to a length of 1/8 inch. 

Fungus gnat larvae are white with little black heads.
