However, why beetles change the color of shells still puzzles scientists. Some researchers believe that the change of beetle skin color is related to its self-protection function-the humidity is high at night, and the beetle turns the shell color black, which is beneficial to combine with the night environment. Other researchers believe that the color change is related to the beetle's heat absorption at night, and related experiments are still being explored, but the research of Belgian scientists explains the basic principle of this phenomenon-the color change of its shell is related to the humidity and light of the environment.

Marie Lasater, a researcher at Namur University, said that the structural features of this beetle are an important "smart material", which can be widely used in human life, such as humidity sensors and humidity level monitoring in food processing plants, with a bright future. Scientists say that they will find out the principle of shell discoloration as soon as possible and benefit mankind as soon as possible.

Beetles are called the strongest creatures that can change color in the world.
