Why are american burying beetle endangered

Aside from monitoring the beetle's situation and defending its habitat in general, the Center has been working hard to stop the proposed Keystone XL pipeline, which would've devastated some of this creature's last remaining habitat as well as habitat for many other rare species, like prairie dogs, whose carcasses are prime burying-beetle sustenance.

Shockingly, despite its absence from most of its range — plus ongoing habitat destruction from the oil and gas industry and new information that climate change is decimating the species in the southern Plains — in the Trump administration downlisted the American burying beetle from "endangered" to "threatened" status.

As part of this ongoing research, and in an attempt to establish another beetle population, biologists have released laboratory-raised American burying beetles on Penikese Island in Massachusetts, historical habitat of the animal.

Burying beetles are unusual in that both the male and female take part in raising the young. Male burying beetles often locate carcasses first and then attract a mate. Beetles often fight over the carcass, with usually the largest male and female individuals winning.

The victors bury the carcass, the pair mates, and the female lays her eggs in an adjacent tunnel. Within a few days, the larvae develop and both parents feed and tend their young, an unusual activity among insects. Brood size usually ranges from one to 30 young, but 12 to 15 is the average size.

The larvae spend about a week feeding off the carcass then crawl into the soil to pupate, or develop. Mature American burying beetles emerge from the soil 45 to 60 days after their parents initially bury the carcass.

Adult American burying beetles live for only 12 months. Historical records offer little insight into what type of habitat was preferred by the American burying beetle. Current information suggests that this species is a habitat generalist, or one that lives in many types of habitat, with a slight preference for grasslands and open understory oak hickory forests.

However, the beetles are carrion specialists in that they need carrion the size of a dove or a chipmunk in order to reproduce. Carrion availability may be the greatest factor determining where the species can survive. Biologists have not unlocked the mystery why the American burying beetle has disappeared from so many areas.
