Bring Out Your Dead!
Bees die after about 6 weeks. And those that live like to keep a tidy hive.
Usually the worker bees will drag the bodies of their fallen brothers & sisters out of the hive and fly off a bit to drop them away from the hive. But it's been raining, and bees don't like the rain, so they've deposited the cadavers on their front porch for the time being.
