Human Itch Mite (Scabies mite)
Scientific Name: Sarcoptes scabiei var. hominis
Order & Family: Order: Sarcoptiformes, Family: Sarcoptidae
Size: Microscopic; females are approximately 0.30 to 0.45 mm long, while males are about half that size.
Natural Habitat
The epidermis (outer layer) of human skin, particularly in areas with skin folds such as between fingers, toes, and on wrists.
Diet & Feeding
The mite feeds on dissolved skin cells and extracellular fluid produced by the host's skin during burrowing.
Behavior Patterns
The female mite burrows into the upper layer of the skin to lay eggs. This creates tiny, raised, wavy tunnels or tracks. They are primarily transmitted through direct, prolonged, skin-to-skin contact.
Risks & Benefits
Risks: Causes scabies, characterized by intense itching (often worse at night) and a pimple-like rash. Scratching can lead to secondary bacterial skin infections like impetigo or cellulitis. There are no ecological benefits known for this parasite.
