This very conspicuous species occurs throughout Europe, from lowlands to high altitudes, from Spain north to Scandinavia and east through Asia Minor to Russia. It is a local insect of sandy, generally open habitats and open wooded areas and clearings. The adults may be abundant where found and are very active; they run rapidly and adopt the typical staphylinid defensive posture when alarmed, with the head and abdomen raised and the mandibles open. They fly readily and resemble a large humble bee in flight. The adults are active from April to October with a peak of activity in mid-summer. Mating occurs in mid- or late-spring and larval development is rapid; pupation occurs in mid-summer and new generation adults are active in late summer and autumn. Both the adults and larvae feed upon various insects but the adults seem to be specialist predators of Aphodius species. The adults are strongly attracted to horse and cattle dung where, on arrival, they will run rapidly over the crust inspecting any crevices or holes for the presence of other beetles; when found they are pulled from the dung, turned onto their backs and dismembered, generally the head is bitten off before they are consumed. Although generally occurring on open and bright dung pasture they also inhabit other dung including that if sheep, goat and deer etc. as well as being occasionally found among carrion or compost, all habitats rich in insects and their larvae. There is little evidence as to where the adults overwinter but it is thought that they move from open situations to marginal habitats in lightly wooded areas. In Europe the adults have been reported entering hymenopteran nests.
