Dried Mucus or Phlegm (Not a Bug)

Commonly found on tissues, handkerchiefs, clothing, or household surfaces.

N/A (Not a living organism)

This is an inanimate object derived from respiratory secretions which dehydrates and hardens over time, often taking on irregular, amorphous shapes that can sometimes be mistaken for larvae or soft-bodied insects.

Generally harmless, though it is a biological waste product potentially carrying bacteria or viruses if fresh; no ecosystem benefit.
