A butterfly is a strong symbol of metamorphosis, with distinct stages. The butterfly is a reminder to make changes when the opportunity arises. Change and transformation are inevitable for us all, but it does not have to be traumatic. Butterfly symbolism is also closely tied to the idea of spirits and souls. It has been used in many religions and cultures.
Psyche is the Greek word for both soul and butterfly.
The belief was that butterflies were human souls searching for a new reincarnation, which gave the creature uncanny and sometimes ominous connotations. This symbolism was also used in early Christianity as a symbol of the soul. Celts thought that women became pregnant by swallowing butterfly souls. These butterfly-souls flew about seeking a new mother. Other cultures believed that spirits of the dead took the form of white butterflies.
