Seen in the visible spectrum, can all bees will look uniform. In the infrared spectrum, it is clear that some bees is warmer than others. Some glow bright orange like hot coals, heat radiating heat to their surroundings. Other is dark and cool.



Heat is concentrated in one central area of the hive brood nest, where young bee pupae grows. A bee that appears relatively still, when looked at in the infrared luminous bright orange, revealing its role as a specialist heater bee.

Bees warmed up itself by vibrating its flight muscles-vibrations, which allow it to warm up to 44 degrees Celsius, former trøde to be high enough to kill it. Other, which seem to catch a quiet Snooze is actually a little tight balls of fire to act to keep the brood warm.

More than two-thirds of the hive honey goes on central heating of the colony. A rarely seen moments caught on camera, after a tired heater bee peaked at a brændselsoverførelsesudstyr bee just returned from root vegetables.

By controlling the temperature, heater control bees young fate. Incubated at 34 degrees, newly born bees is expected to be humble housekeepers, but kept just one and a half degrees warmer, they can instead turn to intelligent and high foragers, live up to 10 times longer.
