Corps et pattes noirs, élytres et massue des antennes rouges, une tache rouge aux angles antérieurs du premier segment thoracique. Abdomen rouge. Écusson aussi large que long. Corps bombé sur le dessus. La larve est de type « ver blanc », le corps blanc, mou et allongé, la tête et les pattes sclérifiées (dures), jaune-orangé.
Facilité d'identification :
Pour spécialiste/difficile
Confusions possibles :
Plusieurs autres espèces de genres proches présentent des colorations similaires, particulièrement Coprimorphus scrutator (Herbst, 1789) qui est plus grande (au moins 8 mm) et moins bombées au-dessus, mais aussi Aphodius fimetarius (Linnaeus, 1758) et Aphodius cardinalis (Reitter, 1892), de même taille, qui ont l'abdomen noir.
Biologie/Éthologie :
Les adultes comme les larves sont coprophages, principalement dans les excréments des herbivores. Les adultes se nourrissent et se reproduisent à l'intérieur des bouses et des crottins, puis les femelles creusent des puis verticaux dans le sol directement sous les excréments, en y enfouissant un peu de matière fécale sur laquelle elle pond ses œufs. Les larves écloses s'en nourriront et se transformeront en nymphes dans le sol. Les adultes sont capables de détecter la présence d'excréments à de très grandes distances, permettant aux jeunes émergents de rapidement s'alimenter.
Biogéographie :
L'espèce est connue de toute la France continentale (Corse exclue).

The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.

Current distribution in metropolitan France
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.

Certain presence
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
Probable presence
This status is based on one or more of the following criteria:
search of species incomplete but presence of supportive environments;
ecology of the species consistent with the hypothesis of his presence;
the last reliable sighting is older than 10 years compared to the reference date, no recent specific research and no presumption of extinction from that date [vertebrates, invertebrates and plants well studied (rhopalocera, grasshoppers, dragonflies ...)] ;
the last reliable observation being older than 20 years, no recent specific research and no presumption of extinction from that date [poorly known taxa: fungus, many invertebrates...].
Probable or certain absence
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
intensive but unsuccessful targeted research;
lack of adequate environments;
unobserved species while its presence is easily detected;
unlikely presence for historical or biogeographical reasons.
This status must be assigned to a department in which the presence of the species is casual.
Absence due to a proven extinction
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
No information
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
