Butterflies signify being healthy

When I see a butterfly floating around with its different arrays of beautifully colored wings. I think of being carefree in paradise.
Based on the ecosystem, seeing butterflies signifies a healthy environment because their presence indicates that there are other life forms around. Butterflies contribute to the World through pollination, as well as, providing the service of being a natural exterminator for unwanted bugs.
