I thought it looked very much like Andrena tibialis, but when I read the commentary on the garden safari site it speaks of being a spring time specie..

Their behaviour was strange or rather new to me. They stayed with many individuals on the same flower spike of Lythrum salicaria among the wild vegetation on the border of a small lake. They were rather slow in their movements , not busy like a 'normal' bee. They looked 'friendly'..
