Nice shot except for one small detail. It's not a bee, it's a fly (one pair of wings not two)!! It's Eristalis tenax, the honey bee mimic. Think of the Golden Syrup tin and the parable of the bees emerging from the corpse of the lion. This is the fella responsible. They lay eggs in decaying corpses and the adults emerge on mass. No sting, totally harmless and adults feed on nectar like bees.
