The local 'butterfly lady' had gone away on a vacation, and left all her caterpillars with our daughter. These were just some of the hundred or so she was caterpillar-sitting at the moment....
When the caterpillars metamorphosis into a chrysalis, they first spin a web attachment to the top of their container, which they then hang from, and then they actually split and shed their skin to reveal the chrysalis INSIDE - they don't spin a cocoon around themselves. Then the chrysalises are carefully removed and hung along the bottom of a shelf for two weeks, where they can be watched.
Just before the butterfly is ready to emerge, the chrysalis looks black, because the casing has become transparent, and we can see the butterfly markings inside. This time we actually got to watch a butterfly emerge. it usually happens so fast that we miss it - one minute there's a chrysalis, the next the butterfly is out with wings expanded - so it was a special treat....
After two hours the butterfly was transferred into a mesh 'butterfly box', and taken outside to be released. Our granddaughter likes to dress up in her monarch butterfly costume for the release.
At this stage the butterflies will sit quietly on a finger to be transferred to a flower.
