Early Bumblebee was the first bee we saw. Then caught a Solitary mining bee (which I didn't get a pic off when in the hand). Don't think we were given the name for that one.
The next one we caught was I think quite a good one - Red-girdled Mining bee (andrena labiate)
I know we saw Red Mason Bee, which I thought the below photo was a phot of, but not sure now.
The last one we saw I think, if my notes are right. Lasioglossum leavigatum, it is a mining bee that was caught for all to see.
It was an enjoyable walk and think I might go there again to have another look around.
I have a few more walks and trips planned for the next few months so will update when I go on those.
