Describing life processes of caterpillars through a hands-on approach, this book explains their lifecycle and that they are the larvae of butterflies and moths. It emphasises the importance of identifying the plant on which a a caterpillar is found, so that it can be fed the right food. It looks at how caterpillars avoid predators, for example, how they may hide rolled up in leaves, be camouflaged to look like twigs, or store poison in their skin. The caterpillar's hibernation and butterfly migration are also illustrated in this book, which is one of a series which gives simple instructions explaining how to find, indentify, collect and study specific minibeasts. It also shows how to make a home, feed and care for them, how to release them successfully back into the wild, how to keep observational records of daily lives and where to find out more.
