Butterflies are beautiful but they have some very odd habits - welcome to their secret world. Did you know that butterflies taste with their feet, do a dark-red poo when they come out of their chrysalises and that some drink the tears of crocodiles? They are a mystery: how does the world look to them, do they ever sleep and how are some of them able to fly so high? This book will open your eyes to these magical creatures around us.
