Description: The Pygmy Snaketail is one of our smallest and rarest dragonflies. It is a very small clubtail with a deep green thorax lined with black, and a black abdomen with pointed yellow lines on all segments. The hindwings are distinctively marked with amber at the base. Its size is 31 - 34 mm (1.2 - 1.3 inches).
Similar species: Its very small size, amber-colored hindwings, and green thorax with a black, yellow-marked abdomen, is unlike an other dragonfly.
North American Range: There are disjunct populations in the northeast, Great Lakes, and southern Appalachians. In Virginia, it is known from a few southwestern counties along the New River.
