As you can see from the photograph taken today the tubes are still sealed. The bees are not ready to come out yet. It is quite a lengthy performance for them to get out. There are approx 5 - 10 bees to a tube. Each grub has its own space filled with pollen and sealed with mud. When the bee at the back wakes up it will chew through the mud and bite the bottom of the bee in front to wake it up. I jest not. This works right the way through the tube until the one at the front wakes up, chews thru the mud and every bee in that tube is free. Its a little bit like an escape from prison!
I am a little worried for these bees and it has been lovely and warm, so there will be stirrings in the tubes. We are expecting an extreme drop in temperature here and possible snow at the weekend. I will cover them if necessary, I have never had to do this before, so havn't decided what with yet. Hopefully they will all be okay. As soon as they come out I will try to photograph them.
Have a great weekend.
