Capping the cell
Eventually the cell is capped. The time taken to cap the cell varies. Queen cells are capped after about 7 1/2 days. Worker cells are capped at about 9 days and drone cells about day 10.
Of course, cells are used for more than brood. Bees will cap honey cells and do so in a couple of ways. “Wet cappings” are placed on the cell such that the cap touches the honey stored in the cell. “Dry cappings” leave a tiny air pocket between the surface of the honey and the underside of the cappings. Dry cappings tend to have a lighter color than wet cappings.
