I have been picking my raspberries and found that bumbles that stay out too late and it gets too cold to fly just spend the night under a leaf or large raspberry till moring and you cannot dislodge them.
Yesterday as I was putting berries in my bowl I was surprised to see a large wasp attached to one of the berries I dropped in the bowl. Now he seemed to be as surprised to be dropped in the bowl as I was to put him there.
After a bit of finagling, I got him on a twig and dropped him back into bush.
He was in no hurry to leave.
