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.
