Parasitidae is a family of predatory mites in the order Mesostigmata that has worldwide distribution.

Relatively large for mites, their color is often yellowish to dark brown.

The family as a whole preys on a wide variety of microarthropods and nematodes, with individual species usually having a narrower range of prey.

[1][2][3] The subfamily Parasitinae is normally found in nests of small animals or insects or in decaying organic matter, from seaweed to forest litter.

These mites disperse via phoresy in the deuteronymph stage of their life cycle.
