I got the idea for this book on an outing with the Sussex Wildlife Trust. We visited a farm where they’d set up a “moth trap” overnight – it was basically a box with a light inside it, where the moths had congregated the previous night. I was struck by the variety of moths, and asked the experts if gaudy caterpillars ever hatched into dull moths and vice versa. The story grew from the answer, which was Yes.

It’s brilliant that Michael Blencowe, from the Sussex Wildlife Trust, has written the little non-fiction book about moths and caterpillars which accompanies The Woolly Bear Caterpillar.
