The wanna be bee

This volucella, a kind of hoverfly, pretends to be a bee as a camouflages.
The female enters the wasp's nest and put her eggs there without being noticed. Later the larvas eat what the wasps bring inside the nest and even dead wasps. As grown ups most birds mistake them for being bees or wasps.  This one could drink the nectar without any disturbance except the click click from my camera :-)
