The seasons of butterfly activities are different in different places. As the temperature drops, butterflies migrate back to the south, where they can be seen all year round.

Butterflies are warm animals, and their body temperature changes with the ambient temperature. Therefore, the butterfly's life activities are directly controlled by the external temperature. It stopped when the temperature was low.

Every morning in early spring or late autumn, in the field, we can often see some butterflies spread their wings and warm themselves against the sun, and they will not start to move until their body temperature rises to the required starting point.
