The desert whitetail is found in Arizona, California, Colorado, Delaware, Kansas, New Mexico, Oregon, Texas, U.S. Virgin Islands, and Washington. It also can be found in Mexico. This dragonfly species can be found near ponds, lakes, and seepage pools in desert areas. In California, the desert whitetail can be found in all its deserts. Desert whitetails fly generally fly from early July to early September. This whitetail also has a flight season from April to October. The desert whitetail will eat almost any soft-bodied flying insect such as mosquitoes, flies, butterflies, moths, mayflies, and flying ants or termites. The naiad of the desert whitetail feeds on many aquatic insects, including mosquito larvae, other aquatic fly larvae, mayfly larvae, and freshwater shrimp. It also eats small fish and tadpoles. Desert whitetail naiads live in submerged aquatic grasses and sedges. They do not actively chase after their prey but wait for it to pass by, a strategy which affords them protection from other predators. These naiads will emerge as adults at night. Adults generally fly from summer to fall. They sometimes fly from spring to winter. The desert whitetail perches on twigs and rocks. This is where the hunting occurs. The male will establish and defend territories at their choice breeding locations. After both genders mate, the female flies singly, without the male attached, to lay her eggs. She does this process by dipping the tip of her abdomen in the shallows of desert seeps and ponds while hovering above the surface of water.
