Alien on Earth: New research suggests that a body-snatching parasitic fly might be the culprit in the decline of the honeybee population in the U.S.

The parasitic fly lays eggs in a bee’s abdomen. Several days later, the parasitized bee bumbles out of the hives—often at night—on a solo mission to nowhere. These bees often fly toward light and wind up unable to control their own bodies. After a bee dies, as many as 13 fly larvae crawl out from the bee’s neck. The bees’ behavior seems similar to that of ants that are parasitized—and then decapitated from within—by other fly larvae from the Apocephalus genus.
