Burr Comb

Bees produce several waxy comb versions.

Comb for baby bees and honey storage measures five cells per inch.

Comb built to hatch drones, or male bees, are larger measuring four cells per inch, more the size of a ladybug.

When honey comb is damaged, bees build new comb in the larger cell size. I also find burr comb on the bottom of frames.

How do you suppose they know what size to build?
