Aphodius fossor

Aphodius fossor
vicinity of Minot, Ward County, North Dakota, USA
July 4, 2004
Size: approximately 10 mm
Aphodius fossor is the largest species of Aphodius in North America. The genus Aphodius is quite common in various dung, especially cattle, and is characterized by a very expanded clypeus covering the mandibles from above, and by having two or more ridges (carinae) running transversely on the meso and metatibia. I have found this species to be one of the most common scarabs in dung throughout North Dakota.
