Unraveling Brood Parasitism in Predatory Mites
Many animal species add their eggs to the brood of other species to benefit from the latter's brood care. This is called brood parasitism. Researchers recently studied brood parasitism in two predatory mite species and found that the parasite mite adds its eggs to the host eggs only under the threat of egg predators but not otherwise. This could mean that brood parasitism in these mites is dependent on the risk of egg predation.
