===Introduction===
Psoroptes ovis are astigmatic, non-burrowing mites around 750μm (0.75mm) in length, and oval shaped. They are extremely pruritic, and cause a contagious skin disease, as well as a loss in body condition. They also cause the host to rub and bite the infected areas, causing further trauma.
===Hosts===
Sheep, cattle, goats, horses, rabbits, and camelids.
===Life Cycle===
The eggs are relatively large, and within around 2 days transform into a hexapod larva. The larvae then moult into a protonymph , which then subsequently moults into a tritonymph. Finally the tritonymph moults to become a mature adult.
Each stage takes around 2 days to complete. The total duration from egg to adult, takes around 10 days, but this figure can longer
===Identification===
*Males identified by copulatory suckers and paired posterior lobes
