In this little book an attempt has been made to discussthe more abundant and widely distributed butterflies ofeastern North America from the point of view of theirlife histories and their relations to their surroundings. Inso doing I have of course availed myself of the writtenrecords of a host of students of butterflies, without whoselabors no such volume would be possible. Among thesetwo names stand out preëminent—William H. Edwardsand Samuel H. Scudder. Each was the author of asumptuous work on American butterflies to which all laterstudents must refer, both for information and for inspiration.Many others, however, have made notable contributionsto our literature of these ethereal creatures.
