>Can bees use honey stores to build comb or only nectar. I read that they use nectar to make into wax, but I was wondering if they will use extra honey stores to get the same result?
If it's stored, they don't need was to store it. They build comb when they need comb. They need comb when there is a influx of food needing storage. So usually that's nectar, but if they are robbing a hive, it's honey. They have no reason to use THEIR stores to build storage.
