This is a picture of the beetle nicrophorus investigator. Every year I catch a number of these in my moth trap always with the 'bugs' as seen on the underside. Can someone tell me if these are young or some kind of parasite? Many thanks.

The 'bugs' on the beetle are

The 'bugs' on the beetle are mites, most likely phoretic mites, they are not parasitic they are hitching a lift to the next item of carrion the beetle finds to lay its eggs on. The mites feed on the eggs and larvae of flies, which reduces the competition for the larvae of the beetle.
