The beetles usually arrive singly at carrion. Sexton Beetles are found on carrion and often bury small dead animals (rodents, birds, etc.) The relationship between the mite Poecilochirus davydovae Hyatt and its burying beetle carrier (Nicrophorus vespilloides ) was investigated.Beetles experimentally stripped of deuteronymphs of Poecilochirus had larger apparent clutch sizes than beetles carrying mites. Those that do live off carrion have a good sense of smell. Nicrophorus investigator, also known as the Banded Sexton beetle, is one of several large orange and black banded beetles found in the British Isles.These brightly coloured beetles can be up to 25mm long and are strong fliers, often being attracted to lights set to attract moths at night.

Nicrophorus vespilloides 3 the host material where they are fed by both parents during the first instar when their mouthparts are small and soft. Silphids have just 3 or 4 exposed segments, and the wing cases are longer than these exposed segments; whereas the Staphs have 3 to 6 exposed segments, and the wing cases are always shorter than the exposed segments. Next the female digs a small passage off from the carcass and lays her eggs. Nicrophorus investigator with mites.

Mixing happens when Nicrophorus species 136 gather to feed, for example on larger carrion (Brown and Wilson 1992). Many phoretic mites travel on scavenger insects and are highly specific; they will arrive on a particular species of host and no other. So they use the beetle as a mode of transport between breeding opportunities: they don’t feed on the beetle itself, and are consequently ‘phoretic’. Around the World.
