This may be a tricky question but I’ll ask it anyhow.
That arc that is sometimes left or created by the bees in the super above the brood (presumably for the queen to lay in), seems to me to have honey in it that is not capped. Sometimes I understand the cells may be completely empty, but I have from memory, only seen honey in the cells - say half filled and uncapped.
Is that honey -
a. honey that was previously capped and had the capping removed (so the honey is actually dried)?
b. honey that was recently added to a previously empty arc of cells, with ripened honey all around it?
c. none of the above, but another possibility?
It seems to me that if it were scenario b. , the bees would have to have left a patch of empty cells from the start of filling the super, which seems less likely to me.
