Both my hives had a few flying bees today. 6C on the "bee thermometer" next to the apiary. I think this is about their limit when it comes to cold. They've had a big kicking-out session of old bits of bee, dead bees, a couple of propolised moths, a harlequin ladybird (alive but very unhappy - stung?) and some kind of fuzzy stuff which may once have been a larger moth of some sort.
There were a couple of dead bees blocking part of the mouseguard. Being a slide-in type of guard, I removed it for a while and scooped out the obstruction. Several guard bees gave my gloves what-for whilst I did this, so it was obviously warm enough outside for them to get aeriated. Later in the afternoon the temperature dropped again and it started to sleet... so I guess that will be the girls' last outing for a while. It is amazing though how they keep the place tidy even during a bad winter.
