When is the best month to visit Dali Butterfly Spring?

Dali Butterfly Spring, the spring water is as clear as a mirror. Every year during the Butterfly Festival, thousands of butterflies come from all directions and fly all over the sky beside the spring. The butterfly is as big as a palm and as small as a copper coin. Countless butterflies also have hooked legs and whiskers, holding each other head to tail, hanging in a string from the acacia tree to the water. The Butterfly Spring, which Xu Xiake has heard about for a long time, can be summed up in its "three wonders": mountain spring, butterflies, and trees. The Butterfly Festival is held every year on the 15th day of the fourth lunar month. At that time, thousands of butterflies fly from all directions and fly all over the sky by the spring, holding each other head to tail, which is a spectacle.
