Not a bug/insect (Debris or Mold)

Typically found on surfaces, stagnant water, or decaying organic matter. Can also be household dust/lint caught on a surface.

If fungal, it consumes decomposing organic material. If debris/lint, it does not feed.

Stationary. If biological (mold/fungus), it grows by spreading filaments (hyphae). If debris, it moves only by air currents or physical disturbance.

Generally harmless debris. If mold, can cause respiratory irritation or allergies in sensitive individuals. No direct bite or sting risk.
