Looks like Andrena hattorfiana - a species that specialises in collecting the pollen of Knautia (Scabious) sp. Smile

Too thought that Andrena, but that I see:

Or mistaken?

Hmm, not too sure - on second thoughts it does look smaller that Andrena hattorfiana but it is difficult to gauge the size with such a close-up photo.

Hi Gansucha, it should be Lasioglossum sp., as far as I can see on the pic, there are basal row of hairs on tergal segments. At Andrena (and Halictus) they are located at the apical end.
Best regards, Marc
