Coprini, might be Heliocopris, but only the major males are good for identification.
Most Heliocopris are quite large, 3-5cm. There is pronounced sexual dimorphism within the genus, with males usually sporting horns or protrusions of different sizes on their head or thorax.
Females lay eggs nearly 5 mm in size, the largest among the Scarabeidae. Eggs are laid one at a time in a tunnel dug directly beneath the dung, containing some of the dung to feed the larva.
Males use their horns, which may be more or less elaborate, to fight over females.
