Explanation of Names

Dellacasa et al. (2002) presented a key to the three species of the A. lividus-complex occurring in the New World.
e US to CA / Mex. to S. Amer. - Map, Nearly worldwide distribution. Introduced into the U.S. from S. Amer. (1)(2)
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)
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)
Stebnicka (2009b: 35) synonymizes Labarrus pseudolividus with Labarrus cincticulus ( Hope, 1847) (p. 284), which she refers to as Aphodius (Labarrus) cincticulus . Théry and Bordat (2012: 311) reject this synonymy based on L. pseudolividus being in predominant use in a large body of literature. They also recall that L. cincticulus has for a long time been considered a synonym of Labarrus lividus ( Olivier, 1789) (p. 86), with the definitive separation between L. lividus and L. pseudolividus being established in Angus et al. (2004). We have chosen to follow Théry and Bordat (2012). - TreatmentBank
