Antennae are bristlelike, shorter than the head, and not obvious. Their wings are dark, with five light spots. Shore flies are stronger, faster fliers than fungus gnats, but they have less of a tendency to take flight in comparison with the more easily disturbed fungus gnats. Larvae have no distinct head capsule, but their dark mouthparts and internal organs may be visible through their outer skin. Shore fly larvae have a distinctive forked, dark-tipped breathing tube at their tail.
Shore flies have several generations each year.
Moth Flies Moth flies are also called drain flies, filter flies, or sewer flies. Moth flies indoors are commonly observed resting with their wings held rooflike over their body on bathroom walls and around drain surfaces. They are somewhat flattened, have a distinct head, and small suction discs along their underside for adhering to slippery surfaces. Larvae feed in decaying organic matter, commonly within drains on the gelatinous film underneath drain plugs and screens and inside of pipes. March Flies March flies are usually dark brown or black, although the midbody of some species is reddish or orange.
