Bees are very difficult to identify from photos, Kev, and probably impossible from those small images. I could make a few random guesses but that is all they would be.

The first one tends to remind me of a Robber Fly (Asilidae) by the general shape but I can't put a name to it. They are something of a specialist subject.

Morning Kevin,

the first is a Mosquito (need a specimen for species + 80x mag.), then a Colletes species, I wouldn't like to try naming the third without further views of a cleaner individual and the last is a male Andrena (need a specimen for species).

Take care,

Jason

That's Great!
Thank you both very much!

Thanks,Kev.
