Abstract: For animals in which parents provide food to their offspring, young often communicate their need to parents through elaborate begging behavior. Using a multispecies approach involving 3 burying beetle species, we show that offspring that are highly dependent on parental provisioning invest the most time in begging for food, whereas offspring that are nutritionally independent invest the least time in begging. Parents, in turn, are highly divergent in their provisioning behavior.
