Itch Mite or Scabies Mite

Human skin, specifically within the stratum corneum (outer layer) where they burrow.

Feed on skin cells and extracellular fluid by dissolving them with enzymes.

Females burrow into the skin to lay eggs. The life cycle involves egg, larva, nymph, and adult stages, occurring entirely on the host. Spread primarily through prolonged skin-to-skin contact.

Causes scabies, a highly contagious skin infestation characterized by intense itching and a pimple-like rash. No ecological benefit; primary risk is human discomfort and potential secondary skin infections from scratching.
