Chrysalis

Late last summer I took 4 Large White caterpillars from the garden and along with a load of nasturtium leaves put them in a Tupperware in the greenhouse. They grew rapidly , then pupated into 4 beautiful chrysalii? 
I have been watching them carefully as the days get longer and the weather warms and on Easter Sunday my first Large White hatched! I was so excited I set it free from the greenhouse without taking a photo.
I am now trying very hard to capture a time lapse of the next one hatching but no joy so far. This is the one I'm focusing on but I've a feeling a different one may hatch first :) I love that I can now see the wings through the casing.
