Phagophilia

Not to be confused with Pagophilia.

Phagophilia or phagophily is the behaviour of feeding on parasites. It is also an example of cleaning symbiosis.^[1][2]

Austrian arachnologist Max Beier reported on phagophilia in pseudoscorpions. Many pseudoscorpion species co-exist with packrat species, and two of them are known to feed on packrat ectoparasites, to mutual benefit.^[3][4]
