That's a really good spot Tweetypie, I have never seen one (except in a round jigsaw puzzle belonging to my Great Grandmother, that I remember completing as a teenager!)
The bee situation is terrifying. I must admit I find it quite hard to distinguish between bee varieties, above the obvious ones. The only thing I can hold onto is that where I am in Portugal we have unlimited hectares of tended/untended land with a huge variety of nectar sources, much of it wild. Which is lucky as locals do tend to be heavy handed with pesticides, or to plough between the productive trees (there is virtually no arable here, its all smallholdings of productive trees sometimes underplanted with veg).
