Re: something isn't right
Do you have more photos? It's hard to see what you are asking about. I uess it would be what looks like the comb eaten through? I would suspect some sort of critter, like a mouse or something. But, mice usually work on the bottoms of combs, in my experience, and away from where the bees are.
Was this comb at the top of the hive? Had the cover been torn off or blown off?
I don't see shb doing this sort of thing. Or wax moth. Maybe robbing bees. But I don't think so. I'm not sure. It's still a mystery.
The answers are the end. The questions are the journey. Journey on.
