Don’t worry – I won’t be posting too many updates on Colin the caterpillar, now chrysalis. I just thought it was interesting to see how quickly he has changed from looking like a caterpillar to looking like a moth-in-the-making. During Monday morning, after he’d just pupated, he squirmed around a lot, sometimes quite violently. By the end of the day, he had turned a wonderful golden brown colour and showed definite structural signs of the moth he will become, a process that will apparently take between two and three weeks.
