Sarcoptes scabiei (De Geer) - (scabies mite)

The mite causes scabies (also called sarcoptic mange) on humans as well as in domestic and a wide range of wild animals. The mite burrows into the skin resulting in intense allergic itching and skin infections. It can weaken the animals, contributing to early death.

There are several subspecies or varieties of this mite specialized on different hosts. Based on DNA analyses, authors have come to different conclusions on whether to regard them as part of one species or as separate species. They are listed here as "varieties":
