Originally published in three volumes in 1953, 1958 and 1975, this book has long been out of print but has now been reprinted by the University of Toronto Press. These are NOT photocopies but are high quality scans - the interior pages are on acid-free paper. The cover is a deluxe-quality hardcover but is not the same as the original.
The Odonata of Canada and Alaska describes and keys out 189 of the 210 species of Odonata found in Canada and Alaska, with two additional species described (but not keyed) in the addenda of volume three. A majority of the species names are up to date, twenty species have had their species name changed or were placed at subgenus level, and have been elevated to genus status.
Each of the 189 species has its own, very detailed description. Includes species name, author, synonyms, a brief summary of the description, then a detailed description of the male and female, wing venation, measurements of wings and abdomen, and a description of the naiad where possible. Also describes the habitat and range, distribution in Canada, field notes, and variations in species where possible. The series contains 153 black and white plates, illustrating various physiological differences between similar species, including abdominal and thoracic markings, male and female terminal segments, hamuli, and illustrations of naiads and their identifying characteristics.
