Orange

I'm not sure, if it was a European orchard bee, buzzing to the poppies.
It was much bigger and had a rather orange butt, but only a smal part.
Nevertheless, it suited perfecty to the poppies :-)
It was only a very short visit. Obviously she didn't like paparazzi  :-D

Edit, thanks to R.: It's a female red-tailed bumblebee
