Richard Jones is an entomologist and writer - he has a way with worms. And before some bright pedant chips in, there are plenty of quite legitimate insect worms: glow-worm, wood-worm, meal-worm, horn-worm, wire-worm, silk-worm, inch-worm.

Calvin Ure-Jones has been on face-to-face and hand-to-bug terms with natural history all his young life, so when it came to drawing picture of insects he was raring to go.
