dorsata_drone_worker

It seems that as the workers get larger, the difference in size between workers and drones gets smaller. Here you see the drone (top) is only 1 mm longer than the worker, in Apis dorsata (the giant honey bee). There is also no cell size differences between worker and drone cells!
In the dwarf honey bees (A. florea and andreniformis), the difference between the two is the largest, both in terms of body size and cell size.
