I'm sharing this link because the decline of honeybees has been something that greatly troubled me. It appears that scientists and the military have jointly discovered a pair of factors - a virus and a fungus - involved in cases of catastrophic hive collapse.
And just to add to the language/culture content of the day, I'll point out that bees have a systematic form of dance communication that allows them to tell where a food source is and how good a source it is. They dance on the honeycomb in figure-eight or split-circle patterns, waggling their little abdomens. I studied it in my linguistic anthropology course, when we were looking at language-like behaviors in animals.
