Scabies Mite (or Itch Mite)

The epidermis (outer layer) of human skin, specifically burrowing into the stratum corneum.

Feeds on dissolved human tissue and skin cells within the burrow, not blood.

These mites are obligate parasites. Fertilized females burrow into the skin to lay eggs, creating serpentine tunnels (burrows) visible as fine, dark, or silvery lines. The lifecycle from egg to adult takes about 10-14 days. They are most active at night, which correlates with increased itching.

Risks: Significant health nuisance. Infestation causes intense, intractable itching (pruritus), especially at night, and an allergic rash. Scratching can lead to secondary bacterial infections like impetigo or cellulitis. Highly contagious through prolonged skin-to-skin contact. No ecological benefits as they are strictly parasitic to humans.
