So Here is a reference to the virtues and how I see it. Through lifes changes a butterfly contributes to our eco system as well as provides us the vision of beauty through seeing them. 

Seeing them creates feelings of humbleness - eye butterfly

In all stages they are charitable to the eco system that gives back - caterpillar

Innocence in a cocoon - Chastity

Kindness as they spread there wings and carries and spreads pollen. - Flying butterfly

Patiently crawls & eats before its time to go into its next stage of life. - worm/ caterpillar stage.

Diligence to transform from one stage to the other coming out of cocoon.- Butterfly/Cocoon

To become, and transform from its four different identities knowing at any stage they are here to also be food or could cause death to another source reflects on temperance. - Butterfly

Hope this is what you were asking for Amy. I hope everyone can see how their virtue can represent either side of the spectrum we call life.
