Fungus Gnat species Mycetophilidae sp
The Fungus Gnats are small to very small gnats. Their thorax is always rounded effecting in the animal always looking downwards. Most species have long legs, but a segment is always going upwards. In most species one of the segments is thickened. The larvae of some species are specialized on fungi, others live in decaying leaves. The specialized ones enter a fungus from the middle or top, for that is the place the eggs are deposited. The ones living in leaf litter often enter the toadstools from the base. Without microscope it is very hard to tell the various species apart.
