Aphodius zenkeri Germar, 1813       Notable B
Widespread throughout England north to Yorkshire with records also from North Wales. A very local species generally found in deer dung in open wooded areas, will also utilize other types of dung (e.g. horse) but then usually in areas where deer are present. Locally we have found the species in horse dung in Whippendell wood where Muntjaks are common. Often found alongside other species e.g. A.sticticus Panzer. Adults appear in June and are present until October.
In the field might easily be overlooked for small fimetarius Lin. or A.foetens (Fab.) but the elytral sculpture is distinct under a lens.

4.5-5.5mm. Glabrous. Head and pronotum black or very dark brown with at least lateral margins lighter. Clypeus obtusely angled in front of eyes then straight to anterior margin, strongly concave anteriorly. Fronto-clypeal suture with central tubercle, rugose in front of this. Pronotum very convex, punctate throughout and not bordered in middle of basal margin. Scutellum equilateral. Elytra red or light brown with indistinct darker marks in apical half, gently dilated behind middle. Striae bordered by raised lines and a row of shiny punctures, interstices convex. Intervals (not striae) 7 and 9 discreet at apex, not united (A.putridus (Four.)) , and flat. Legs and basal segments of antennae and palpi red.

Aphodius putridus is superficially similar but smaller, 2.5-3.5mm. Intervals 7 and 9 are united apically and raised into an obvious fold.
