Red mason bees

Red mason bees are very active in our garden today, especially on the rosemary shrub.

I noticed this small bee in a spider web on our window sill. The bee had been caught in the web by its legs, the wings were not entangled.

I used a stick and carefully released the bee. I think it might have been a tawny mining bee, I did not get a good view and photograph not clear enough to be certain.
