What service do mites from the genus *Poecilochirus* provide to carrion beetles at a carcass site?

Answer

Consuming the eggs and tiny larvae of competing flies

As soon as the mites disembark onto the carcass, they immediately start consuming the eggs and tiny larvae of competing flies, ensuring a larger food supply for the beetle's own larvae.
