It covers 77 of the 138 species of damselflies known in North America, making it a very useful guide for the entire United States. Each species account includes:illustrations of as many forms (male, female, juvenile, mature, and color morphs) as possiblecommon and scientific names, with pronunciationdistribution mapkey featuresidentifying characteristicsdiscussion of similar speciesstatus in Texashabitat, seasonality, and general commentsIn addition to photographing damselflies in the wild, the author and illustrator have developed a new process for illustrating each species by scanning preserved specimens and digitally painting them. The resulting illustrations show detail that is not visible in photographs. The book also contains chapters on damselfly anatomy, life history, conservation, names, and photography, as well as a list of species that may eventually be discovered in Texas, state and global conservation rankings, seasonality of all species in chronological order, and additional resources and publications on the identification of damselflies.
