metamorphosis

The butterflies came out today.  Are they the babies starting out a new life or are they the elderly, entering the last stages of life, albeit able to breed?
Do they hatch or do they emerge?

Have  you noticed that the bottom part of the wing is transparent?  

Anyway, enough philosophy for today.  They are really quite pretty, very like the chrysalis.  Here it is, on the banana passionfruit plant.
