The leaf-cutter bees have now stopped filling the 8-9mm holes in my bee house. There are spare 8-9mm holes in that bee house and another new bee house.
Is it likely that any more bees will be coming along this year?
My Leaf-Cutters are still hard at work Mike, the Mason bees finished nest building at the end of June.
Conditions seem to be very favourable at the moment so I think they may continue building for a while.
Thanks. The Mason Bees had filled all my larger holes by mid-June, we then found all the mud doors broken in quite deeply, 99% probably by a Greater Spotted Woodpecker that comes to our peanut feeder.
I cleared the remainder out and added 13 mm wire mesh, 37mm forward of thre canes, to keep further birds out.
Then the Leaf-Cutters came and filled a lot of holes, but that has almost stopped now, hence my question about August.
