Description
Appearance
The Common Baskettail is a medium-sized emerald, about 36 to 44 mm (1.4 to 1.7 inches) long. The body is brown to olive, with a fairly hairy thorax and a distinct dark amber or brown triangular patch at the base of each hindwing. The eyes are green or blue-gray in life and meet at a seam on top of the head, as in other emeralds. This listing is for a female. Females are similar in color to males.
Habitat and Range
Common Baskettails live at lakes, ponds, marshes, and slow rivers or streams. The species is widespread in eastern North America, from southern Canada through much of the eastern United States, including Wisconsin. Our specimen was collected in Douglas County, Wisconsin.
Behavior
This is one of the earliest dragonflies to appear in spring. Males patrol over open water. Adults often fly in loose swarms and are swift aerial hunters, preying on flying insects.
Life Cycle
This species has incomplete metamorphosis, with egg, aquatic naiad, and adult stages. The naiads are aquatic predators. Adults emerge in early spring, and the flight season runs mainly from spring into early summer.
Economic Impact
Common Baskettails are beneficial predators of mosquitoes and other small insects. They are not pests and have no significant economic impact.
Taxonomy
Epitheca cynosura (Say, 1839) belongs to the emerald family Corduliidae, genus Epitheca (baskettails). It was originally described as Libellula cynosura.
This preserved specimen educates on dragonfly biology and wetland insects, suitable for displays or studies.
