Unclear—likely a tiny springtail or small fly fragment

If a springtail, it commonly inhabits damp soil, leaf litter, compost, bathrooms, and other humid surfaces. If a small fly, it may occur around decaying organic matter or indoor drains.

Springtails feed mainly on fungi, algae, decaying plant matter, and microbes; small flies may feed on decaying organic material or microorganisms.

Springtails favor moisture and may jump using a forked furcula; they do not bite. Small nuisance flies typically crawl or fly weakly near moist organic residues.

Springtails are harmless to people and help decompose organic matter. Most comparable tiny flies are nuisance insects rather than disease threats, though large numbers can indicate excess moisture or decomposition.
