American Burying Beetle: Family Oriented
These beetles not only are monogamous but also raise their children together. Expectant parents bury dead birds or mice and lay eggs nearby. The parents lie on their backs and use their legs like a conveyor belt to move carcasses up to 200 times their own weight. Once hatched, larvae feed on the carcass or the parents rub their wings together to call the larvae and regurgitate meat into their mouths.
