− | *Dorsal spines
| + | Sarcoptes mites are [[Burrowing Mites|burrowing mites]] of dogs and foxes. They Cause [[Sarcoptic Mange]]. The mites prefer hairless skin and so begin on the hocks, elbows and pinnae. The mites are usually spread by direct host to host contact. |

− | *Female lays eggs in epidermis in an '''egg laying pocket'''
| + | Sarcoptes mites have a '''3 week''' life cycle. The female lays eggs in the epidermis in an '''egg laying pocket'''. The female feeds on liquid oozing from damaged tissue. The eggs then hatch in 1 week and '''6 legged''' larvae are released. They crawl to skin surface and then burrow back into the epidermis into '''moulting pockets'''. |
| + | The larvae moult to become '''8 legged''' nymphs. The nymphs moult twice before becoming adults. Adult males then emerge and look for females to mate. |

| + | Mite infection can be diagnosed with a skin scrape of a 'non-scratched' region. The presence of one Sarcoptes mite is diagnostic. |
