PREFACE

The object of this little book is to afford an outline sketch of the facts and meaning of insect transformations. Considerations of space forbid anything like an exhaustive treatment of so vast a subject, and some aspects of the question, the physiological for example, are almost neglected. Other books already published in this series, such as Dr Gordon Hewitt's House flies and Mr O H. Latter's Bees and Wasps , may be consulted with advantage for details of special insect life stories. Recent researches have emphasised the practical importance to human society of entomological study, and insects will always be a source of delight to the lover of nature. This humble volume will best serve its object if its reading should lead fresh observers to the brookside and the woodland.
