We have 9 caterpillars that have shed their skins and have now transformed into chrysalises. We seem to have 1 caterpillar who is not compiling with the rules and is still wriggling around and having his own party. I will keep you informed on his progress. The children have been fascinated with the transformation but to be honest so have I . They have to settle for 3 days now when I can move them into the butterfly house.
