Yesterday, I checked the hive entrance and found this:
This looks like a wax mot larvae.
This means I will have to open the hive and check the damage inside the brood area. Since the brood is a mess of cross combs, this will be very disturbing to the colony, but wax moth can destroy a colony, so I have to do it.
Hopefully I will have a nice warm day before the winter.
I also saw a drone, surprising at this time of the year.
