Cabbage White butterfly emerging from its cocoon

I found some caterpillars on my nasturtiums and put the in a plastic container with some leaves. After a few days they had all turned to chrysalises. I glued these to a small twig with a dob of Copydex, then placed the twig in the Fig tree in our conservatory. Within a few days they had started to hatch. I was lucky to set up the video camera to catch this footage
