Three species in Britain, all 5-10mm long and one of which, Trox perlatus Geoffroy, has not been seen in the country since the 1930s.  As the common name suggests, these beetles are mainly found in association with dry carcasses, although they are also found in large birds nests, particularly hole-nesting species such as jackdaws Corvus monedula (L.).  The elytra have a distinctively granulate appearance.
