The graceful and flexible butterfly can always attract people's attention. But people always pay too much attention to the beautiful wings of butterflies, and few people observe the structure of butterflies themselves. Compared with the large wings of the butterfly, its body is small and fragile, and it is difficult to see its body structure without careful observation. Many people do not know the knowledge related to butterflies, so here are some of them.

Butterflies can also find their distant companions or mates through their keen sense of smell. Even if the other party is several kilometers away from it, they can chase the smell and find the exact location of the other party.

Butterflies cannot fly in the early morning. When the sun is shining, we can often see butterflies dancing among the flowers, but in the early morning, we can hardly see butterflies. Where have they all gone? It's not that the butterflies don't want to come out, it's that they can't fly at all. Butterflies are ectothermic animals. Their temperature mainly comes from the external environment, that is, radiant heat. These radiant heat are extremely important for the life activities of butterflies and are an important source of body temperature for butterflies.

Butterfly wings are transparent. The butterflies we usually see are brightly colored, because the wings of butterflies are covered with thousands of small scales, these scales reflect light on different colors, so that we can see different colors. The color displayed by butterfly wings is called structural color, also known as physical color.

Butterflies usually live only a few weeks. We always hope that beautiful things can stay with us for a long time, and the same is true for beautiful butterflies. Unfortunately, once the mature butterfly emerges from the chrysalis, the vast majority of butterflies only have a lifespan of 2 to 4 weeks. During this time, they will focus all their energy on two tasks: (1) finding food to maintain their short life; (2) courting, mating and laying eggs as soon as possible, and producing offspring to make a final contribution to the continuation of the population.
