"Feathering into a butterfly". The original meaning refers to the butterfly larva from the chrysalis, after molting, the process of changing into an adult. Butterflies undergo complex changes in their body tissues when they change from chrysalis to adult, so that their morphology and lifestyle are significantly different from those of chrysalids, and they are fully metamorphosed.
The butterfly symbolizes freedom.
