A national group that tracks beekeeping says more than a quarter of the country's 2.4 million bee colonies have been lost. Billions of bees have died with no solid explanation as to why.
The ailment is called colony collapse disorder, or CCD, and it's threatening the livelihood of commercial beekeepers. CCD is being blamed on things like insecticides, mites and even cell phone towers.
Some say the signals from those towers confuse the bees. They can't find their hives and eventually die. So far colony collapse disorder has been found in 27 states.
