Synonyms and other taxonomic changes
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
livid (L). 'ashen, bluish' (1)
Size
Length 4–6 mm
Identification

Det. M. A. Quinn, 2012
Range
e US to CA (CA-FL-MA-OK) (BG data). Nearly worldwide distribution. Introduced into the U.S. (2)
Habitat
Found in a wide variety of habitats (NCSU)
Season
Most abundant from March until October when fly breeding was highest and the forage production was greatest. (NCSU)
Food
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)
Remarks
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.
