"A black insect, with brilliant metallic blue or purple reflections on the under side, and well known as "wheeling its drowsy flight" during fine evenings. This it does in search of a patch of cow-dung, through which it makes its way until reaching the ground, where it bores a perpendicular tunnel about 8 inches deep, and as wide as a man's finger; then ascending to the surface it conveys a quantity of dung to the bottom, and on this it proceeds to deposit an egg; another layer of the same material and another egg follow until the entire shaft is filled." — Encyclopedia Britanica, 1893
