Butterflies have beautiful, wide wings and sometimes gracefully soar, sometimes lightly flutter around flower tips, appearing very lively.
However, if you observe butterfly flight early in the morning, you might be surprised at how clumsy their movements are. They flap their wings vigorously but can’t fly high or fast. Why is this? Is it because they are hungry and lack energy?
No. The reason for the butterflies’ clumsy flight is not that they haven’t eaten enough, but rather the morning chill.
During the day, the ground is heated by the sun, causing air currents to rise. Butterflies take advantage of their sail-like wings to rise with the currents, making their flight quite agile. But in the coolness of the morning, the ground is cold and air currents are not very active, so the butterflies have no external force to rely on. Their large wings, instead of enhancing their flight capability, actually become a burden.
Another reason is the heavy morning dew. Near the ground, water vapor easily condenses on surfaces due to the morning chill. Butterflies often rest in dense foliage, where their wings get moistened by the dew, increasing their weight and making flight difficult.
