 This mixture is regurgitated and presented to the larvae in droplets.Future queens may receive additional glandular secretions, but in terms of total protein, pollen, and carbohydrates in the food mixture, larvae of all castes receive the same proportions.Nurse bees have been observed to feed queen, worker, and male larvae using the contents of the same crop, so it seems unlikely a significant difference exists in the food consumed by larvae of different castes.
