Likely small fly or gnat

Small flies and gnats commonly occur indoors near windows, houseplants, food, moisture, or drains, depending on species.

Adults may feed on nectar, plant fluids, decaying organic matter, or nothing; larvae often consume fungi, decaying material, or other organic matter.

Typically weak fliers attracted to light, moisture, odors, or vegetation; many species have short life cycles and reproduce in damp organic material.

Most are harmless and contribute to decomposition or pollination. Some species can annoy people or infest stored food and houseplants, but this individual cannot be assessed reliably.
