An Ox Beetle losing its balance

Ox Beetles are stout beetles that are quite hairy on their ventral side (belly). They are nocturnal, and therefore usually seen at night. They are dark brown all over. The male Ox beetle has horns growing off of the pronotum (shoulder plate). In young males, they are more like bumps. Females do not have either. Males use these horns to fight over females.

Habitat for this species of beetle is typically pine forests, and they can be found in most of the gulf and Atlantic coastal states. Adults eat decaying tree roots. Nocturnal larvae are C-shaped grubs that hatch from a burrow in the ground. Females lay eggs there and bring leaf litter into the burrow so the newly hatched larvae have a food supply. As they mature, they begin to eat decaying tree roots, just like the grown ups.

Antennae: Beetles have a pair of antennae on the head used as sensors.

Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).

Thorax: Holds the three pairs of legs as well as vital internal organs.
