Gooden's Nomad Bee (Nomada goodeniana) ♂︎
Sandpit Mining Bee (Andrena barbilabris)
Utterly amazing how they find their nest hole without any obvious signs of it on the surface and then just sink through the sand in a matter of seconds.
One female today allowed four matings before she sank beneath the sand.
Quite picky too.
She flew up and around to make sure she had a good number of males following her.
Once or twice when there were only a couple of them she flew up and on again before they had a chance and then flew round until she had more followers.
