My good lady (the queen bee) found this queen wasp in the garden with a mating drone still attached to her.

With the weather close to zero we suspect they had both had succumed to the cold. I can only hope that I go out this way! But when we brought them indoors to photograph - she slowly started to show some signs of life. We were amazed at the size of the queen compared to the drone - she's literally twice as big!
This is the 3rd queen wasp we've found in the garden this winter and this is one queen who won't be hibernating and starting a new nest next year.
