Common Dragonflies and Damselflies of the Pacific Coast

Here's the cover of my new dragonfly field guide.



The guide has a nice feel to it, due in part to the high quality paper that we used, but also to the size and shape of the book that allows it to fit nicely in the hand or pocket.

Here's a peek inside the guide, at the spread for the Comm Green Darner, the subject of the previous post.



Each species has its own spread, and each has a number of helpful features:

• Life Size Photo
• Range Map
• Flight-Season Chart
• Annotated Photos
• Colored Margins

Here's a brief description of each feature:

Life Size Photo (A unique feature in this guide) Dragonfly field guides generally give a numerical value for the size of a dragonfly species. This is fine, as far as it goes, but what's even better is to show the dragonfly at life size right there in the guide. The photo on the left side of the Common Green Darner spread shows the dragonfly at life size—as if it had actually landed on the page. Now you know exactly how big it is.

Range Map The range maps in this field guide are derived from dots maps produced by the Dragonfly Society of the Americas (DSA). The observations in the maps are vetted by dragonfly experts, and provide the current state-of-the-art in our knowledge of dragonfly ranges.

Flight-Season Chart (A unique feature in this guide) The DSA dot maps have dates associated with each observation. I have "data-mined" this information to produce charts that show the percentage of observations for each month of the year. The charts give not only the beginning and ending months of the flight season, as in many guides, but also the distribution of sightings within the season.

Annotated Photos (A unique feature in this guide) It can be hard when you start to do some dragonflying to know just where to find the relevant field marks of a particular species. In this guide, each species has annotated photos that point out exactly where the key field marks are and how to interpret them.

Colored Margins The margins of each spread have a color that is most characteristic of that particular species. Thus, the margins on the Common Green Darner spread are green. By looking for the appropriate color on the margins of the pages you can quickly locate the section where the dragonfly you want to identify is located.

The guide also includes detailed information on dragonfly behavior, and I'll describe some of those features in future posts.

Here's a link to the Amazon page for the book:

It's been a lot of fun writing this book, including as it does so many of my favorite photos and new observations of dragonfly behavior. I sincerely hope it will be helpful in introducing others to the pleasures of dragonflying!
