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.
