The rusty patched bumblebee had been missing from the eastern United States for the past five years - until now. Combing through 35,000 bees collected from Virginia near the Shenandoah Valley and Appalachian Mountains, scientists found a single rusty patched bumblebee worker.
"In 20 years of studying bees, I have never seen a rusty patched," says T'ai Roulston, an entomologist at the University of Virginia who helped discover the bee, in a statement.
