Scabies (/ ˈ s k eɪ b iː z, ˈ s k eɪ b i iː z /; [10] also sometimes known as the seven-year itch) [1] is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, [1] [3] variety hominis.
The condition can be passed from person to person through sexual or close skin-to-skin contact.
The scabies mite Sarcoptes scabiei var. hominis goes through four stages in its lifecycle: egg, larva, nymph, and adult. Upon infesting a human host, the adult female burrows into the stratum corneum (outermost layer of skin), where she deposits two or three eggs per day. These oval eggs are 0.1–0.15 mm (0.0039–0.0059 in) long and hatch as ...

The equine botflies present seasonal difficulties to equestrian caretakers, as they lay eggs on the insides of horses' front legs on the cannon or metacarpal bone (below the knee) and knees, and sometimes on the throat or nose depending on the species.
