Nicrophorinae are well known for the habit of locating a [[Carrion|carcass]] and burying it by unearthing the soil underneath it. The burying behavior has seemingly evolved to prevent competition from other insects such as fly [[maggot]]s. It has been observed that the cooperation of the two parent beetles leads to breeding success. More likely than not a breeding pair will work together, but in cases where there is large [[carrion]] males try to boost their reproduction by emitting [[pheromone]]s. In this way, he will father more offspring, but the reproductive success of the primary female steadily declines. Sometimes, where there is a large carcass the likelihood of intense competition from flies leads to [[cooperative breeding|communal breeding]]. There appears to be a truce between females who would normally compete for the males, and in these cases cooperative behavior extends to females caring for each other's offspring. At the height of breeding season pairs of beetles may compete for the [[carrion]]. The losing pair will be ejected from the [[carrion]] and if any eggs have been laid they are killed so the new female can lay her own.<ref name="essential entomology">McGavin, George C.
