Original combination: Aphodius pseudolividus Balthasar, 1941
Aphodius pseudolividus is part of a worldwide complex of species often lumped under Aphodius lividus (Olivier).
Stebnicka in 2009 synonymized L. pseudolividus under L. cincticulus (Hope).
Explanation of Names

Det. M. A. Quinn, 2012
e US to CA (CA-FL-MA-OK) (BG data). Nearly worldwide distribution. Introduced into the U.S. (2)
Found in a wide variety of habitats (NCSU)
Most abundant from March until October when fly breeding was highest and the forage production was greatest. (NCSU)
Adults are found in a wide variety of 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)
Aphodius pseudolividus is part of a worldwide complex of species often lumped under Aphodius lividus (Olivier). While species of the A. lividus-complex show a number of distinguishing features, they can be subtle. 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. (Extracted from Smith & Skelley (2007) via Scarabaeoidea of Southern South America)
Non-native, introduced from southern South America.
