Description: The male Northern Spreadwing's thorax is dark with very narrow green stripes, and is whitish below. The abdomen is black with a gray tip. The size range is 32-42mm (1.3-1.7 inches).
Similar species: The Northern Spreadwing is nearly identical in the field to the Southern Spreadwing (L. australis). Magnification of male cerci or female ovipositor is required to reliably determine identification. See illustrations in Lam (2004) or Paulson (2011). The Southern Spreadwing is more common and widespread in Virginia, and with a long flight season extending from early April into early November. Formerly, Southern and Northern Spreadwing were considered as subspecies and known as the Common Spreadwing.
North American Range: The Northern Spreadwing lives across the northern United States and Canada. In Virginia, it is only recorded from Bath, Highland, Montgomery, and Prince William counties.
VA Observations by Locality: Montgomery | Bath | Highland | Bath | Highland | Prince William
Flight season and broods: Virginia flight dates for the Northern Spreadwing range from 21 May through 3 October.
Aquatic Habitat: In Virginia, the Northern Spreadwing inhabits vegetated ponds such as high-elevation beaver ponds. In its main range it inhabits a variety of vegetated ponds, lakes, bogs, and slow-moving streams. It is generally restricted to fishless ponds.
Behavior and Ecology: The Northern Spreadwing is typically a late summer to fall species. Like other species in this genus, The northern Spreadwing perches with wings partially spread.
Population trend and potential threats: The Northern Spreadwing is a widespread species in its primary range, but appropriate fishless vegetated pond habitat in Virginia is very limited and should be protected.
Management practices: Monitor and protect occupied habitats.
