Booger / Nasal Mucus (Not likely an insect)

Nasal cavity of mammals (typically humans)

Does not eat; composed of water, mucins, inorganic salts, and immunoglobulins

Secreted by mucous membranes to trap dust, pollen, and pathogens; eventually dries out and expelled.

Biological waste; harmless but generally considered unsanitary. Often mistaken for parasites or small insects due to shape and texture when dried.
