3 week life cycle

Female lays eggs in epidermis in an egg laying pocket

Female feeds on liquid oozing from damaged tissue

The eggs hatch in 1 week

6 legged larvae released which crawl to skin surface

The larvae then burrow back into the epidermis into moulting pockets

Larvae moult to become 8 legged nymphs

Nymphs moult twice before becoming adults

Adult males emerge and look for females to mate

-==Introduction==
-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.

+*Male is about 250μm in length and the female about 400-430μm in length
-Sarcoptes mites are small, round mites. They have short legs that project only a short distance from the body margin. They have dorsal spines arranged in rows and a terminal anus. The male mites are about 250μm in length and the females are about 400-430μm in length.
 ==Life cycle==
+*'''3 week''' life cycle
+*Female lays eggs in epidermis in an '''egg laying pocket'''
+*Female feeds on liquid oozing from damaged tissue
-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 eggs hatch in 1 week
-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.
-==Diagnosis==
+*'''6 legged''' larvae released which crawl to skin surface
-Mite infection can be diagnosed with a skin scrape of a 'non-scratched' region. The presence of one Sarcoptes mite is diagnostic.
+*The larvae then burrow back into the epidermis into '''moulting pockets'''
