Some bees and wasps that host mites have peculiar pocket-like structures called acarinaria.

These have long been considered as morphological adaptations to securely transfer beneficial mites into nests, and thus are thought to be the product of a mutualistic relationship.

However, there has been little compelling evidence to support this hypothesis.

We demonstrated that the parasitic mite Ensliniella parasitica, which uses acarinaria, increases the reproductive success of its host wasp Allodynerus delphinalis by protecting it from parasitoid wasps: an average of six mites led to a 70% chance of mortality, and ten mites led to a 100% chance of mortality.
