Aphodius fimetarius (Linnaeus, 1758)

Female
Common throughout the UK in various types of dung and decaying vegetable matter. Found throughout the year, sometimes in winter flood refuse but most abundant in dung from April and then found throughout the summer. Occasionally found is horse dung throughout Whippendell wood during the spring but abundant on pasture e.g. Common moor in cattle dung and the various fields adjoining the canal southwest of Watford in horse dung from April to October. Specimens are occasionally swept from grassland throughout the Watford area.

5-8mm, width ≥ 2.7mm. Pronotal base continuously bordered i.e. not broken medially, front angles and side borders yellow, with scattered large punctures between 5X and 10X larger than finer ones. Elytra uniformly red or (rarely) with darker marks on disc (ab. punctatus Muls.) interstices smooth, without sculpture (cf. A.zenkeri Germar). Male with anterior depression on pronotum and three prominent tubercles on head.
Distinctive and soon recognised in the field but close to A. foetens (Fab.); anterior pronotal margin not bordered in fimetarius and abdominal ventrites black/dark brown (a good field character), in foetens the anterior pronotal margin is finely bordered adjacent to the front angles and the abdominal ventrites are light brown
