Itch mite (Scabies mite)

Natural Habitat

Human skin, specifically within the stratum corneum (the outermost layer of the epidermis).

Diet & Feeding

The mites feed on skin cells and intercellular fluid by dissolving the tissue as they burrow.

Behavior Patterns

The female mite burrows into the skin to lay eggs, creating 'tunnels' or burrows. This triggers a delayed hypersensitivity reaction (allergic reaction) resulting in intense itching.

Risks & Benefits

Risks include intense itching (pruritus), skin rashes, and secondary bacterial infections from scratching. It is highly contagious through skin-to-skin contact. There are no ecological benefits to this parasite.
