Scarab Beetles are omnivores.

Dung beetles are a type of scarab beetle that live off of undigested nutrients in the excrement of various herbivores.

Scarab larvae eat roots, decaying plant material, dung, and carrion.

Adults feed on fruits, mushrooms, plants, carrion, poop, flowers, leaves, pollen, nectar, and plant sap.

Life Cycle

Scarab beetles undergo complete metamorphosis.

Stages include: egg, larva, pupa, and adult.

Female scarab beetles la their eggs in the underground dung roll.
