Extra Small - _TNY_0244
The subgenus Micrandena are known as the mini-mining bees – obviously because they are smaller than the rest of the Andrena genus.
This one on top of a pink great masterwort (Astrantia major) is a female of either shiny-margined mini-mining bee (Andrena semilaevis) or impunctate mini-mining bee (Andrena subopaca).
Discerning between these small guys is difficult from just a shot like this, but I narrowed it down to two species based on distribution.
