Itch mite

Burrows into the stratum corneum (upper layer) of the human epidermis.

Feeds on human skin cells and extracellular fluid.

Female mites burrow under the skin to lay eggs. Larvae hatch and move to the surface to mature and mate before re-infesting the skin. They are obligate parasites.

Causes Scabies, a highly contagious skin infestation characterized by intense itching and a pimple-like rash. Secondary bacterial infections can occur from scratching.
