“Bumblebees prefer their food warm and learn to locate hotter flowers using color as a cue, scientists say. The findings may have broad implications for the evolution of flowering plants.
To attract insect pollinators, flowers offer a nutritious reward of nectar and pollen. Now biologists say many flowers may encourage visits by offering a “heat reward” as well. By consuming warmer nectar, bees may save energy they would otherwise have to spend maintaining their own body temperature.”
