Bees behaviour i've not seen before

When i was in my garden 2 days ago ,i noticed ,what looked like small
honey bees ,coming in and out of a drill hole in a brick wall ..
there wasn't any sign of bees within the confines of the wall ,,so they must have been within the small cavity in between the bricks themselves.

I thought no more of it ,though i felt it was quite a small area to have a nest at the begining of the summer,,next day i noticed a bee working on something at the hole entrance.
Now a day later (our hottest day/weekend so far this year) the hole
is completely sealed with quite a tough material,almost matching in colour the mortar that it is surrounded by ....and no sign of the bees.
I'm intrigued by this so i thought this could be the best place to mention it to u all ,chris

That sounds like a very good description of the behaviour of mason bees, such as the Red Mason Bee Osmia rufa.
