The front legs are modified for digging. One species, Onthophagus gazella Fabricius, was introduced by USDA scientists in the 1970's and is now common throughout the state. In parts of Texas, they remove 80 percent of the cattle droppings. They are often attracted to lights at night. These beetles are related to the sacred scarab of ancient Egypt, Scarabaeus sacer Linnaeus.
Mouthparts are for chewing.
Larvae feed on animal excrement buried by the adults. Animal excrement is rich in insect fauna and can yield these strikingly beautiful beetles. Beetles can be washed to remove debris. None, they are considered a beneficial insect. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
