The Dipterous family Mycetophilidae is composed of small to medium sized flies, ranging from two to nine millimeters in length. These fungus-gnats are numerous both in species and in number of individuals to be found in a local habitat. Characteristics of the legs that are particularly noticeable are as follows: elongated coxae, thickened femur and, spured and setose tibia. The adult resembles a mosquito in that it has a small head, antennae with twelve to seventeen joints and a highly arched thorax. Predominating colors are yellow and black; the abdominal segments often have alternate bands of black and yellow. The males have a complex hypopygia, which is important in the identification of the species.
