Yes, I tipped a bee the other day, in the porch. I thought it might be dead but just in case it was just 'hibernating' I put it in a sheltered spot from where it could fly off if it came back into life. Some years ago, I was out sailing in mid Irish Sea when a host of flies dropped down dead, legs up in the air, on our boat. A short time later, they all flew off again on the rest of their trip across the water. True.
