We found our first wax moth cocoon today in one of the hives.
That means the larvae has been burrowing into the beeswax comb looking
for impurities, which they live on. They don't eat any wax, but their
little caves can cause honey to spill out, making more work for the
colony to repair.
I wonder if a small wax moth population might have benefits for the
colony by having impurities removed?
