Description |
Dark-winged fungus gnats are small to very small, slender, soft-bodied, mosquito-like flies. They range in size from 1⁄32″to 7⁄16″ (1 to 11 mm) in length, but most are less than 3⁄16″ (5 mm) in length. There are two large compound eyes on the sides of the head and three small simple eyes (ocelli) in a triangle on top of the head. The compound eyes meet above the antennae bases. The antennae are relatively long (for a fly) and have six or more segments. The legs are relatively long. There is a very short cross vein at the wing base but there are no other cross veins. The R1 vein is short and the R5 vein is long. The M vein has a fork with a long stem, and the Cu1a vein has a fork with a short stem. According to BugGuide.net, adults cannot be identified to species short of mounting a male specimen on a slide, applying a chemical, and viewing it under a microscope. The larvae are slender, white except for a black head, semi-transparent, and legless. |
