What is this?

Whispy bits found over the top of a frame in the super. It is in a stack of ready supers with a clear board underneath and on top so in theory nothing can get in. I did find one larvae on another frame. Is this the start of wax moth. It’s the first time I’ve had drawn supers to store. They are all ones that might have a bit of honey in them but weren’t extracted. I haven’t had a chance to go through them all as just wanted to grab a couple of frames for a demonstration. The most full ones are on the top.

Yup, looks like early satges of wax moth frass to me.
Stick frame(s) in freezer for a week or so if really concerned. Usually if a strong colony the bees deal with them.

It is wax moth. If you bend a paper clip and gently turn it under the cells you will probably find all the bottom of the cells eaten away. Hold the frame up to the light, you can often see the runs or even the grubs inside the frames. Me, I would replace it with fresh wax and shove that lot in the solar melter

Needs dealing with PDQ before they go through the whole stack.

Thanks, yes I’ve moved that super. The ones underneath are no where near as drawn out and look ok. I’ve started to make a Solar wax melter. More equipment!!!!!

You have to check the whole stack and preferably get the supers onto the hives. If left untreated and unattended during wax moth season they will be destroyed - supers as well as brood frames.
