Itch mite (Sarcoptic mange mite)
Scientific Name: Sarcoptes scabiei
Order & Family: Order: Sarcoptiformes, Family: Sarcoptidae
Size: 0.3–0.45 mm long (females) and 0.2–0.24 mm long (males)
Natural Habitat
Human skin, specifically within the stratum corneum (outer layer of the epidermis)
Diet & Feeding
Skin cells and extracellular fluid; they consume these as they burrow through the skin
Behavior Patterns
The female mite burrows into the skin to lay eggs, creating tiny zigzag tunnels. This activity is what causes the symptoms of scabies.
Risks & Benefits
Risks include scabies, a highly contagious skin infestation causing intense itching and a pimple-like rash. Benefits are negligible as they are parasitic.
