e US to CA (CA-FL-MA-OK) (BG data). Nearly worldwide distribution. Introduced into the U.S. (1)

Adults in dung
Life Cycle
Eggs are laid singly or in groups inside dung pat.
The dwelling beetle, A. pseudolividus, does not incorporate manure into the soil but directly competes with horn flies for manure resources. (NCSU)
Remarks
Dellacasa et al. (2002) presented a key to the three species of the A. lividus-complex occurring in the New World.
Aphodius pseudolividus can be the most commonly collected species in an area, adults being found in a wide variety of dung. They are frequently attracted to lights, accounting for their large numbers in collections. (Smith & Skelley 2007)
Non-native, introduced from southern South America.
