Apis Posterior (Bee's Bum!)

On a prowl round the garden between showers (yes, yet again!) I popped off a shot of a bee on a Bidens flower. Must admit, I am very glad to see bees doing the rounds as they have been in very short supply this year so far. Can we hope that wasps are also in short supply!
I really must stop these bug-blips before I start on some of the really scary-looking mini beasts that inhabit our homes and gardens.
