This article is interesting, it suggests that in bee colonies there are certain bees that use their bodies to provide heat for the colony. The bees have been dubbed “heater bees” due to the function they perform. Thermal imaging research for a TV series found that heater bees maintain the temperature in the hive where the young bees grow. The young bees called pupae are sealed inside wax cells whilst they grow into adults. Heater bees keep the temperature at 35C for those pupae which will become forager bees and 34C for bees that will be house keepers. The heater bees creep into empty wax cells and transmit heat to around 70 pupae at any time. In this way they can ensure that there are always enough of each type of bee to maintain the hive.
