It comprises around 40 families and apparently originated as parasites of birds before a secondary radiation saw some taxa become parasites of mammals. Because of their parasitic lifestyle members of the Psoroptidia do not exhibit a deutonymph stage.The group contains many of the more notorious parasitic members of the Astigmata.
