Delicate long-legged fly (likely a midge or fungus gnat)

Moist soil, leaf litter, fungi-rich organic matter, and vegetation; adults may occur indoors near houseplants or windows.

Adults commonly consume nectar, honeydew, or little food; larvae feed on fungi, decaying organic matter, plant tissues, or other small organisms depending on species.

Weak-flying, delicate adults are often attracted to light and moisture. Larvae develop in damp substrates, and some species produce silk-like material or webbing.

Most are harmless to people and do not bite. Larvae generally aid decomposition, though some species can damage plants or spread fungal contamination in greenhouses.
