Two colonies had been living in the roof of this house for 60 years.
It is both remarkable that bees decide to live over such a long period of time in a cavity and are well able to manage the nest at their own. Old comb might need to be replaced and draged out. What role does wax moth play for clearing out old comb?
Bees are smart creatures, one can imagine that they might likely accept the 'help' of wax moths by sharing such labour and leave the work to them on unattended eges of comb structure.
Even though bees are remarkebly well studied, little is known about what bees do in natural habitats over long periods.
