Arrenuridae is a family of water mites (Hydrachnidia) in the order Trombidiformes, containing at least three genera and approximately 110 described species. Members are primarily freshwater predators as adults and deutonymphs, with larvae that parasitize aquatic insects. The family exhibits complex mating behaviors mediated by chemical communication, including female-emitted sex pheromones that trigger male responses.
