They come not only in red, fuchsia, orange, pink, blue, gold, saffron, black, emerald, maroon, earth tones, and more, but also in metallic colors. Some have colored, spotted or banded wings; others may have clear wings but clubbed abdomens or a spike on their tail. And, no, they do not sting or bite. They have mouths that they do use to bite their prey (mostly mosquitoes and gnats) but they do not bite people unless caught and handled roughly, and even then it's akin to getting a good pinch. They have no stingers: the projections on the end of their abdomens are their claspers, used by the male to hold the female in their unique 'wheel' mating position.
All you really need in order to be a dragonfly watcher are you eyes. 
However optional items would include shoes that can get wet, an insect net, a 10-20X magnifying hand lens, zip-lock baggies/glassine envelopes, a good guide and plenty of sunscreen. If you don't own close-focus binoculars, then a camera with a zoom lens can also be helpful: often regular ‘birding’ binoculars won't focus in close enough while a camera will. You can click for a picture, or just use the camera for viewing. Some dragonflies need to be caught and held to learn their identifications, thus the net and zip-lock/glassine baggies. Dragonflies and damselflies can be held by their strong wings; folding the wings above their abdomens. Observe them thus in hand or temporarily placed in the baggies, viewing their markings before releasing them. But it is also enjoyable just to watch their amazing aerial antics.
To date, more than 117 species of dragonflies have been identified in the greater Southwest - over 184 if you include the damselflies, the members of the smaller suborder Zygoptera. Our desert habitats have a unique and beautiful dragonfly fauna, often containing species found in no other environment. Desert specialists include the Desert Whitetail, Desert Forktail, Desert Firetail, Mexican Amberwing, Mexican Forktail, Filigree Skimmer, Serpent Ringtail, Brimstone Clubtail, Kiowa and Pima Dancers, Painted Damsel and the very rare Desert Shadow Damsel.
Dragonfly studies in the United States are in their infancy, as the study of birds was a century ago. Believe it or not, just a few years ago a much smaller number of
species of Odonata (the scientific name for the dragonfly's order that includes dragonflies and damselflies) were known to exist in the southwest’s deserts. Many species have been added just in the last few years, mostly though observation of live flying insects. Other species were found through reviews of museum specimens and photographic records. And the census is nowhere near complete; there may be a few surprises yet! Part of the thrill of watching dragonflies is the ability for even beginners to add to the understanding of their distribution, life cycles and habitat requirements. You could easily go out and find a new species in a new locality or observe and record new behavior or flight data! We still have very much to learn and record about their distribution, life histories and flight seasons.
Life Cycle
Like dragonflies everywhere, our desert species start life as a tiny egg, not much larger than the period at the end of this sentence. Most species scatter their eggs freely over a waterway or insert them into vegetation that is floating in or overhanging water. Some eggs hatch within weeks; others over winter before hatching. The larval stage is called a nymph or, more properly, a larva. Dragonfly larvae look like fierce dragons and crawl about underwater hunting for food. A unique feature is their labium, a lower lip that they project to hook prey. While damselfly larvae have feather-like gills at the end of their abdomen, dragonfly larvae do not. All go through about a dozen molts, or instars, before crawling out onto a stem or rock to emerge.
After a period of time, from a month or two to even a few years of growing and molting, the larva crawls out of the water. Its skin then cracks open over the thorax. The adult dragonfly slowly emerges from this old shell; some species even hang down from it limply at first. Then after its legs harden, it pulls itself upright and its body and wings begin to expand and harden. After an hour or more the new adult dragonfly flies off. The empty shell that is left behind is called the exuvia.
Most adult dragonflies live for only several weeks or months; adult damselflies live for an even shorter period. During this time they feed on mosquitoes, gnats and other small insects (at a rate of very many each day); they mature sexually, and then mate.
Male dragonflies defend territories while awaiting the females or actively search for them. When the male finds a female, he grasps the female with the clasp-like holders at the end of his abdomen. Mating occurs in the unique “wheel” position. The females can use ovipositors to insert their eggs into plant stems or just scatter them over the water, sometimes ovipositing while in tandem flight with the male. The larvae that hatch develop without need of parenting.
Unfortunately, you couldn't find a handy guidebook for identifying dragonflies until quite recently. The Audubon Society’s Insects and Spiders field guide could be helpful, but this and other older insect guides cover only a few of the desert species of dragonflies. But, now there is Kathy Biggs’ new guide, Common Dragonflies of the Southwest, A Beginner's Pocket Guide.
It does include the damselflies and almost all of the desert specie of dragonflies. Many of the pictures it includes are by SW desert inhabitants themselves like Doug Aguillard, Bob Behrstock, Doug Danforth, Rosser Garrison, Dustin Huntington, Greg Lasley, Peter Moulton, Bob Parks, and Steve Potter. It uses the new common names that were adopted by the DSA (Dragonfly Society of the Americas) in the fall of 1996 and Common Dragonflies of the Southwest, A Beginner's Pocket Guide is of a size where it can be taken into the field with you.
Beware: all the nature guides written before 1996 use non-standardized common names. It is planned that everyone will now use these new standardized names and that the hobby/study of dragonflying will thereby avoid the confusing proliferation of common names that the butterflies and native plants have developed. both fun to look through and useful.
The Southwest deserts offer many great places to begin/continue the study of dragonflies, and some of the nation’s most beautiful species occur here, such as the Painted Damsel or the Filigree Skimmer. So, just find a spot near water on a calm, sunny day; any natural or artificial body of water will do. Desert parks would always be an excellent destination. The easiest species of dragonflies for beginners to observe and learn usually occur at still waters such as lakes and pond, as they tend to perch, while those along the rivers aren't always so obliging.
Dragonflies need clean water in which to breed, so treat our waterways kindly. To encourage them in your yard, a pond is perfect, and the less fish in it, the better for the Odonata. Native water plants are easy to include, but even ponds with ornamental plants will provide some habitat for them. Short of a pond (even a half barrel will attract damselflies), provide strong perches in sunny areas from which they can pursue their prey. And of course, avoid the use of pesticides! Since Dragonflies eat mosquitoes, even as underwater nymph, they can be used to help control those mosquito species, including those that carry West Nile Disease, but they alone will not completely wipe out a mosquito population.
Like hummingbirds, and unlike the butterflies, dragonflies can maneuver quickly, making rapid zigzag maneuvers. Occasionally though, you’ll find one basking in the sun or claiming and defending a territory on a pond or creek where it can be observed at leisure. Otherwise, enjoy the aerial antics of one of Earth's very first fliers: indeed, they predate the dinosaurs and are among our most ancient creatures.
The following are a few of the most common dragonfly species found the Southwest deserts.
Reminder: 25 mm equals one inch.
Dragonflies:
Dragonflies are heavy-bodied and usually larger than damselflies; their huge eyes are very close together and they are strong fliers. At rest, they hold their wings out flat to the sides, or slightly forward and downward.
