![]() The carcass, though, needs to be a Goldilocks weight between about 80 and 200 grams: Too big and it’s hard for a beetle to bury and preserve too small and it won’t be enough food for many larvae. Ideally, once the kids emerge from the hole, they will sniff out their own wild carcasses to bury and breed without the scientists’ help. When the larvae emerge, they will co-parent-rare behavior for insects-by feeding the dead bird to their young. The two beetles will mate and then lay eggs in a side chamber in the soil. Next, Perrotti dispenses each quail, head lolling, into a hole and covers it. The pair have been carefully matched together using what researcher Brandon Quinby from Purdue University calls “the equivalent of a stud book.” “Here we go, into the honeymoon suite,” says Perrotti, as he drops a prospective beetle couple into a hole. ![]() Since the 1990s, Lou Perotti, the wiry, tanned conservation director at Rhode Island's Roger Williams Park Zoo, and other researchers have been working to establish a second, backup eastern U.S. Fish and Wildlife Service (FWS) listed the species as endangered. In the entire eastern U.S., the only wild beetles left were found on Block Island off the coast of Rhode Island, and by 1989, the U.S. Alarmed, they launched wide-scale surveys. But entomologists only noticed the losses in the 1980s. Today, it survives only in scant patches across about 10 percent of its historic territory.Ĭollection records show that burying beetles disappeared gradually over the 20th century, starting at least as early as the 1920s. The quails are for the American burying beetle, an inch-long carrion eater that once thrived across 35 U.S. Conservationists have carried out this odd ritual every year here for the last quarter-century. On a Monday in late June, as the Massachusetts resort island of Nantucket abounds with vacationers who use the word “summer” as a verb, a small team plants dead quails in about two dozen man-made holes on a grassy moor. This story isn’t about a bird it’s about a hole that a bird once filled.
