Dragonflies and Damselflies: Model Organisms for Ecological and Evolutionary Research ReviewThis 20-chapter, edited volume synthesizes much of the research that has been conducted on dragonflies and damselflies. Divided into two sections (one on ecological studies, the other on evolutionary/life-history studies), this book has chapters written by prominent researchers in the field of odonatology. It provides concise reviews of topics such as odonates as indicators, conservation, life-history tradeoffs, and sexual selection.
The book's target audience is for other odonatologists, and it would be extremely valuable for students just getting started in that field. However, its steep price (rather remarkably so, given the lack of color photographs and slim size) may make it prohibitively expensive for students on a budget. I anticipate that my copy will be borrowed frequently!Dragonflies and Damselflies: Model Organisms for Ecological and Evolutionary Research Overview

Dragonflies and Damselflies of the West (Princeton Field Guides) ReviewBasics: 2009, 535 pages, softcover, 850+ color photos of all 348 species in western US and Canada, range maps
This is an exceptional book for any dragonfly enthusiast with a focus on identification. This is the most complete and best quality of any related book available.
As noted in the title, the "West" refers to all species found in (a) Alaska, (b) Canadian provinces of Manitoba and Nunavut and all provinces west, and (c) N/S Dakota, Nebraska, Kansas, Oklahoma, Texas and all other states west. This region encompasses 348 species, all of which are shown in this book.
All photographs are in color and of very good quality and size. All but 4 or 5 of the species are shown with at least 2 photos. Many species have 3 or 4 photographs. The photos show differences between male and female, adult and immature, and variations due to pruinose and heteromorphs. These photographs will be very helpful with the identification of most odonata you encounter - except for those frustratingly similar species. This is where the detailed text will be very informative and useful.
The text, ranging from ½ to a full page for each species, consists of 6 distinct sections. The bulk of the material is found in Description, Identification, and Natural History. A single, yet potent, sentence is given to each of the other three sections of Habitat, Flight Season, and Distribution.
The identification section does a good job of comparing similar species, giving pointers of how to differentiate between the finer points. The description of each can often be very detailed, which might be a bit too detailed for the novice or a person with a passing interest to know what to call that dragonfly flitting around the garden. To truly identify down to the species level, the book often describes the individual with terms of lateral thoracic stripes, postocular spots, abdomen black above S2-7, and other necessary "scientific" descriptors.
Expanding on this detail are wonderful drawings of the abdominal tips and appendages, which are sometimes the only means for identification.
The book has other brief sections on research, collecting, naming, anatomical labels (to help with terms in the identification section), and natural history.
Lastly, a distribution map is supplied for each individual. Where relevant, the maps zoom in to the restricted ranges for many of the species. The boundaries for the states and provinces are shown, which help with better detail.
This is, by far, the best odonate book available for the US. I certainly hope an eastern companion will follow in the near future.
I've listed several related books below...
1) Common Dragonflies of the Southwest by Biggs
2) Dragonflies and Damselflies (Odonata) of Texas, Volume I by Abbott
3) Dragonflies and Damselflies of Texas and the South-Central United States by Abbott
4) Dragonflies and Damselflies of California by Manolis
5) Dragonflies & Damselflies of the Border Southwest by Behrstock
6) Dragonflies of Alaska by Hudson
7) Dragonflies through Binoculars by Dunkle
8) Dragonflies And Damselflies of Georgia And the Southeast by Beaton

Dragonflies of North America: A Color and Learn Book With Activities ReviewNot too long ago I noticed dragonflies around my swimming pool. They were multi-colored and had fascinating antics. About the time of my dragonfly discovery, I heard a lecture was to be given at the Santa Rosa Garden Club about dragonflies, so I attended the lecture, orchestrated by Kathy Biggs. Dragonflies are her passion and she has studied them for years. She is one of few individuals quite knowledgeable on the subject, you might say she's an expert. She displayed a coloring book with pictures of many Dragonflies of North America. The book is not only a delightful coloring book, but is an accurate educational tool. I purchased one for my 5-year-old grandson who was immediately enraptured! Not only is there a great variety of dragonflies to color, but careful descriptions are given to help one distinguish the various kinds of dragonflies. I would encourage anyone whose boy or girl is interested in garden creatures, nature or coloring to purchase one of these books. The book is reasonably priced, considering it is has an educational nature as well as fun. It lends itself to crayons, colored pencils or colored markers.
