Wonderful watching them fly in the spring sunshine, isn't it?
I managed to waste hours of the weekend just watching them. Saw at least 4 different colours of pollen going in. There is still a little bright red stuff from the last of the snowdrops and some pale greyish pollen from the helleborus. Also a couple of shades of yellow, I think at least some from the catkins and there is quite a bit of blackthorn flowering so guessing some from that too.
Good luck for the honey harvest.
