The images in this panel were taken using only the warm natural light available on the site. This makes the images somewhat grainy, which is not out of keeping with volcanic ash.
A cabbage white caterpillar crawled up my balcony wall and became a chrysalis. In spring the butterfly was visible though the chrysalis shell. One day a tiny foot could be seen protuding from the top. I grabbed a ladder and my camera. It took about an hour for the butterfly to emerge and another hour for it to stretch and dry its wings.
