Starting from ten the drowsy bugs count down to zero as each of them drops off to sleep. With sleepyheads to identify on each page, whether they are a woolly caterpillar or a firefly, this is a book for the curious reader who loves images of stink bugs in stripy trousers and sweet potato weevils fast asleep on a pile of crackers. But, if anyone's still awake at the end ... it's time to turn back to the beginning and start counting again.
