Non-insect material (likely salt, keratin, or food residue)

Commonly found on floors, fabrics, or skin surfaces in domestic environments.

Does not consume nutrients as it is not a living organism.

Stationary and inanimate; the crystalline structure and irregular shape suggest it is a fragment of salt, dried biological residue (like a scab or callus), or food crystalline substance.

No biological risks from an insect standpoint; however, if found in unusual quantities on the body or bedding, consult a professional to rule out hygiene or dermatological concerns.
