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. It overwinters as an adult in litter or woodland edges in sunshine. The pronotum is hairless, hind legs are straight, anterior orange markings on elytra usually more or less continuous across the suture (but not always), with fine golden hairs at the tip of the abdomen only. Adult body length is 10 - 15 mm. The mites on Nicrophorus are not always beneficial: Blackman, S. W. 1997. The adults are good fliers. De Gasperin, O.

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. No evidence of a cleaning mutualism between burying beetles and their phoretic mites. The larva is the typical woodlouse-shaped Silphid type (see the drawing at the top of the page), and is shiny black with a yellow edge. It is a member of the genus Nicrophorus or sexton beetles, comprising the most common beetles in the family Silphidae.This species is a decomposer feeding on carcasses of small dead animals.

Paul Radford, Assistant Warden Members of this family are often referred to as large carrion beetles to differentiate them from the many other smaller beetles to be found at carrion e.g. Like the burying beetle, these mites depend on carrion to breed but lack the capability of locating a carcass themselves. They occur throughout the world and number about 200 species in 15 genera and 2 subfamilies; Nicrophorinae Kirby, 1837 and Silphinae Kirby, 1837. Drumnadrochit, Inverness, Scotland, UK, August. ... Mites and birds: diversity, parasitism and coevolution. Mites associated with Nicrophorus (Silphidae: Nicrophorinae) beetles provide a model system to explore species boundaries and cryptic diversity, as well as host specificity and coevolution. Adults are most commonly seen between April and October. Antennal club orange. doi:10.1371/journal.pone.0150969. 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’. When the larvae have grown, the parents leave, at which point the mites climb back on board and journey with them to the next rotting corpse. The adults bury carrion and small dead animals as food for themselves and their larvae. Edward Island, and Nicrophorus investigator is newly recorded in New brunswick.

The time from egg to adult takes about a month, and it pupates in the soil. You can see part of its wing sticking out of the elytra. Nicrophorus beetles are associated with at least 14 species of mites representing four families, and these mites can occur at high prevalences, with up to 95% of a given beetle population carrying mites (Wilson and Knollenberg, 1987).
