Science Online Butterfly Chapter

There is a layer of extremely fine scales on the butterfly's body. Don't underestimate these very small scales. These are the protective umbrella for the butterfly to regulate its own body temperature. Whenever the temperature rises and sunlight shines on these scales, these very small scales will automatically open to reduce the radiation angle of the sunlight, thereby reducing the absorption of sunlight heat energy. When the outside temperature is too low, , these scales will automatically close, allowing sunlight to directly shine on the scales, so that enough heat can be absorbed. In this way, even if the temperature changes greatly, the butterfly can still control its body temperature within a normal range.
