Leiinae

Leiinae is a subtribe of flies belonging to the family Mycetophilidae, commonly known as fungus gnats. This subtribe is within the tribe Leiini. Flies in Leiinae are typically small and slender, often found in damp environments such as forests where fungi grow. They are characterized by specific morphological features of their wings, antennae, and other body parts, which are used by taxonomists for identification and classification. The larval stages of Leiinae species usually develop in fungi, decaying organic matter, or other similar substrates, playing a role in decomposition and nutrient cycling within their ecosystems. Identification to genus and species level often requires expert knowledge and microscopic examination of specimens. The classification of Leiinae, as with other fungus gnats, has been subject to revisions over time based on new morphological and molecular data.
