What causes size variation in bumblebee workers? In pollen storing species larvae develop in individual nest cells and are fed directly by adults. Thus, adults probably
determine
the size attained by each larva. Bumblebee larval cells are not as neatly organized as are those of honeybees, and larvae at the periphery of the brood may receive less care than others. Some researchers may thus believe that ten-fold variation in worker mass results from the accidental neglect of some larvae. However, given that larvae are reared in a controlled environment by specialized nest workers, it seems more likely that this size variation has an adaptive function and that the colonies benefit from rearing workers of a range of sizes.
