There was much excitement ( for me!) in the royal nursery, yesterday. The first caterpillar successfully negotiated its way to adolescence. I noticed in the morning that one of the caterpillars looked as though it was ready to make a cocoon. I checked again about 2 in the afternoon but nothing had changed. I checked again about 3 hours later and the job was done. I am slightly miffed that I missed the chrysalis process. I need to watch more diligently when I see the next caterpillar preparing for its metamorphosis.
