Just wondering if anyone has seen burr comb like this? It was at the top of the hive under the inner cover and there was a bit of it there. Removed a little to photograph it. Never noticed anything like it before. I would say it has a distict salmon pink colour to it mainly at the edges and spots throughout that looked like mould as on mouldy bread. Does anyone think it is an issue?
I agree with your thoughts, some kind of mould. I had some old comb that was slightly discoloured in the same way. I wouldn't worry about it though. Bees have evolved with mould in hives. If they don't like it, they will toss it out.
