Back above the water, but still small, the American Burying Beetle is monogamous and also participates in a parental relationship with the young.
The U.S. Fish and Wildlife Service puts it this way: "It is a warm, midsummer night. Two creatures find a small, dead animal and begin to bury it underground by gradually excavating soil out from under it. Once in the underground chamber, the creatures strip the fur or feathers from the carcass, roll it into a ball, and coat it with secretions, preserving it in a semi-mummified state. They mate. Later, the carcass will be food for the entire family."
While it sounds simple, it's not always the case. The male beetles must fight for the carcass and attract a mate at the same time. Usually the largest male and female beetles win the carcass and then move it like a conveyor belt, laying on their back and shifting it with their legs.
In this way, the two beetles can move material 200 times their own weight. Once they've buried their romantic prize and mate, they later go on to tend to up to 30 young in a brood.
Before you begin to feel inadequate, know the spend only a week feeding off the carcass before they crawl into the soil to finish their development, emerging fully mature a month or two later.
