“The Dragonfly meaning changes with each culture. The main symbolisms of the dragonfly are renewal, positive force and the power of life in general. Also, the dragonfly frequently represents change. And as a dragonfly lives a short life, it knows it must live its life to the fullest with the short time it has – which is a lesson for all of us.
In Native American astrology, there is a strong belief that each person has a totem animal spirit which serves as their guardians and guides through certain phases of life. Often, an individual would have many different totems throughout life, some for just a time, some for their entire lives. And one of these totem spirits was the spirit of the dragonfly. It would adopt men and women, young and old. The dragonfly spirit means you must consciously make an effort to express your hopes, dreams, needs and wishes.” taken from ~http://moderndragonfly.webs.com/dragonfly.htm
