7mm long, numerous, with other Andrena mining bees.
No interactions present.
Checked my photos and noticed the male of this species matches Lasioglossum albipes- but I haven't checked all the other options yet so please correct me if I'm wrong,
(this one was great as there were three different species of mining bee and two Nomada present in one square metre of south facing bank...)
