Food relocation behavior, nests, and brood balls of canthon quinquemaculatus laporte de castelnau (Coleoptera: Scarabaeidae: Scarabaeinae)

Individuals of Canthon quinquemaculatus Laporte de Castelnau rolled balls up to 4 m from the food source. Stealing balls was common. Male headstand position was observed at the entrance of chambers containing a rolled ball and a female. Nests were shallow, telecoprid, and compound. Male and female c...

Stealing balls was common. Male headstand position was observed at the entrance of chambers containing a rolled ball and a female. Nests were shallow, telecoprid, and compound.

These characters might be useful to distinguish fossil brood balls constructed by necrophagous Scarabaeinae from those constructed by coprophagous species. Fil:Cantil, L.F.
