We have been watching our caterpillars daily for changes. This week we have observed that our caterpillars have grown in size. And today we were very excited to see that 2 of our caterpillars have attached themselves to the underside of the lid. We watched in amazement as one of the caterpillars spun round and round to shed their exoskeleton then slowly harden into chrysalides. Toby said, “ He is spinning his cocoon”.
