Butterflies As part of our theme of lifecycles at pre-school, we’ve been learning about the journey of the caterpillar to chrysalis to butterfly… Our very hungry caterpillars arrived on 19th April 2018 8 May 2018. The caterpillars have become chrysalises and are all settled in their cocoons. We can’t wait to see them emerge as butterflies! 17th May 2018. Wow what an exciting afternoon – watching one of our butterflies emerge from its cocoon. 21st May 2018. All our butterflies safely hatched and have been released today but stayed long enough for us to watch them for a while.
