HURLEY, N.Y. (AP) — While scientists have documented cases of tiny flies infesting honeybees, causing the bees to lurch and stagger around like zombies before they die, researchers don't know the scope of the problem. Now they are getting help in tracking the honeybee-killing parasite from ZomBee Watch, created in 2012 by John Hafernik, a biology professor at San Francisco State University. The afflicted bees often make uncharacteristic night flights, sometimes buzzing around porch lights before dying.
