The dot-tailed whiteface is a small dragonfly with a length of 1 to 11/5 inches (25 to 38 mm). It is distinguished by the mostly black body, small black basal wing spots, black legs, and white face. Male dot-tailed whitefaces have one yellow spot on the dorsal side of the abdomen. Female dot-tailed whitefaces have multiple yellow spots along the dorsal side of the abdomen and the last yellow spot is large and square shaped. There is also a small yellow stripe along the lateral edge in the middle of the abdomen. In both sexes, the abdomen has been known to fade when they age.

Flight Season
This dragonfly is most active through early May to late August.
Naiad

Adult
This dragonfly species will eat almost any soft-bodied flying insect including mosquitoes, flies, butterflies, moths, mayflies, and flying ants or termites.
Ecology
Naiads live in submerged vegetation. They don't actively chase prey but wait for it to pass by, a strategy which affords them protection from other predators. Naiads will emerge as adults at night. The adults generally fly from early June to early August, its sometimes different months. This whiteface prefers warmer habitats than many other whitefaces, and is often found sitting on lily pads in heavily vegetated ponds. It hunts from the shoreline vegetation, which this species perched on.
Reproduction
After mating, the male will actively guard the female with whom he has mated by flying above her while she lays her eggs. He does this to prevent other males from mating with her. A female lays her eggs by dipping the tip of her abdomen in the water while hovering just above its surface.
