Mystery of the Dying Honeybees

I'm concerned about the news that honeybees are dying off mysteriously around the United States and Europe. It's so weird: I noticed a dead bee yesterday on my front steps, and another one today out in the garden. When I saw the second one, it made me do a double take, because (and I know this is a little gross) there were no other bugs around it. Usually, when something dies like that, nature takes its course and the bug is fed upon almost immediately by other bugs. Not this time.

Strange...
