Appearance
The Dot-tailed Whiteface is a small skimmer, about 29 to 33 mm (1.1 to 1.3 inches) long. Like other whitefaces, it has a pale face, a mostly dark body, black legs, and a small dark patch at the base of each wing. It is named for a clear yellow or yellowish-white spot on the top of abdominal segment 7. This listing is for a male. Mature males are mostly black, with that single pale spot on segment 7. Females have more yellow markings along the abdomen, but they share the same prominent spot.
Habitat and Range
Dot-tailed Whitefaces live at vegetated ponds, lakes, and slow waters, including farm ponds. The species is widespread across southern Canada and the northern United States, and it is common throughout Wisconsin. Our specimen was collected in Douglas County, Wisconsin.
Behavior
Males defend small territories at the water’s edge and often perch on low stems or floating plants. Adults also bask on the ground in sunny clearings. Like other dragonflies, they are swift aerial hunters and prey on flying insects.
Life Cycle
This species has incomplete metamorphosis, with egg, aquatic naiad, and adult stages. The naiads are aquatic predators. In Wisconsin, adults fly from mid-May to late August.
Economic Impact
Dot-tailed Whitefaces are beneficial predators of mosquitoes and other small insects. They are not pests and have no significant economic impact.
Taxonomy
Leucorrhinia intacta (Hagen, 1861) belongs to the skimmer family Libellulidae, genus Leucorrhinia (whitefaces).
This preserved specimen educates on dragonfly biology and wetland insects, suitable for displays or studies.
