Explanation of Names
Common name coined based on the scientific name. It seems appropriate, based on the large eyes of this species.
Size
13-20 mm
Identification
Black, note large eyes (for this genus), about half as wide as long. Clypeus (forehead) toothed. Large, up to 20 mm. Compare C. pilularis (=C. laevis), which has smaller eyes and is slightly smaller. See print references.
Range
Eastern and central United States
Habitat
Typically open areas, pastures, attracted to dung
Season
March-July (and later?) in South Carolina
Food
Adults associated with dung for breeding--unclear if they feed on it.
Life Cycle
These are dung rollers. The ball is buried and the female oviposits on it. Adults attracted to lights, which most Canthon are not. (1)
