Rainbow scarabs are dung beetles and live in and eat piles of animal scat (poop). The parents dig burrows under the animal droppings and take a little down into the burrow, where the female will lay her eggs. When the babies hatch, they devour the dung.

Any place animals poop; especially cow pastures.
Rainbow scarabs are only about an inch long.
