American Burying Beetle aka Nicrophorus americanus

Although it once ranged from Nova Scotia to Florida, the American Burying Beetle's last native population east of the Mississippi is now found only on Block Island. The inch-long insect was added to the Endangered Species list in 1989, and in the early 1990s a successful program to breed and reintroduce the beetles to selected habitats was initiated at Roger Williams Park Zoo.
