Pupae of drones (honeybee). Here we see drones in various stages of development. On the left, a stretched prepupa (age 11 to 14 days from the egg being laid). At this stage the cell is already capped. After 14 days, the prepupa has shed its skin, and the final form of the bee can be seen. At first, it is all white (second from left). Later it starts to gain colour, first with the eye, then the whole pupa. The developing bee remains as a pupa from 15 days after the egg being laid until day 24. In the background is a foundation wall of wax imprinted with cells for the workers.
