Hi Driesl, welcome ! Nice to meet another 'Gentenaar' over here! Thanks for the correction!
I've just read your comment on the Flemish Nature Forum too. There you say that Osmia rufa usually has a later start off in the year and that its hair is more brownish.
Is the white hair on its head the key for it being a male?

Another Osmia cornuta, I guess, from today. I saw one that was much bigger (2x) with the same vibrant red hairs on the abdomen, unfortunately didn't manage to take its pict.
