Scabies Mite
Scientific Name: Sarcoptes scabiei var. hominis
Order & Family: Order: Sarcoptiformes, Family: Sarcoptidae
Size: Microscopic; females are typically 0.30–0.45 mm long and 0.25–0.35 mm wide, often barely visible to the naked eye as a tiny white/brown speck.
Natural Habitat
The epidermis (upper layer) of human skin, particularly in warm, moist folds like finger webs, wrists, elbows, armpits, and the genital area.
Diet & Feeding
Feeds on human skin cells and fluids found within the epidermis.
Behavior Patterns
Female mites burrow into the upper layer of the skin to live and lay eggs creating microscopic tunnels (burrows). The life cycle from egg to adult takes about 10-14 days. They are most active at night, which coincides with intense itching.
Risks & Benefits
Risks: Highly contagious skin infestation causing intense itching (especially at night) and a pimple-like rash. Scratching can lead to secondary bacterial infections like impetigo. There are no ecosystem benefits as they are obligate parasites.
