Kids often spot woolly bear caterpillars creeping across the ground in fall, but these furry-looking creatures seem to disappear as quicklyas they pop up. Where do they come from in autumn, and where do theygo? In fact, they live throughout North America all year long. In vividstorytelling style, Laurence Pringle uncovers the secret life of the woollybear caterpillar, following one caterpillar as she feasts, tiny and hidden, inthe tall summer grass; molts and grows; then sets off on the fall journeywhere she's most likely to be seen. Packed with surprising details (did you know that woolly bears can survive freezing temperatures by producinga natural antifreeze?), this book will appeal to every child who's been luck yenough to spy one of these beloved caterpillars—and to anyone who'd like to.
