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.
Stages include: egg, larva, pupa, and adult.
Female scarab beetles la their eggs in the underground dung roll.
There are more than 35,000 species of Scarab Beetle worldwide.
In the United States and Canada there are over 2,000 species.
They range in size from 1 millimeter to 160 millimeters.
Their legs have teeth on the outer edges.
They walk awkwardly due to their strong, heavy legs which are great for digging.
Most of them can fly.
They weigh up to 3.5 ounces or 100 grams.
