The male Desert Forktail has a greenish face and a blue-green thorax with a yellow shoulder stripe. Abdominal segments are black and orange, with the tip (segments 8-10) blue. Females are paler than males, but have similar markings.

This is a southwestern species just reaching southern Kansas with adisjunct population in Lancaster County, Nebraska, 200 miles to thenorth and east. The first record for Nebraska was a largepopulation found in 1937 at Capitol Beach in Lincoln. The specieswas thought to be extirpated but was rediscovered in 2000 and is abundant at several sites in the city. A good accessible site, Dakota Springs, is near exit 403 off I-80. The best site may be the ditches along I-80 at Capitol Beach, but they are not easily accessible. All sites are associated with highly alkaline streams. At Dakota Springs a tiny stream with very saline water flows in a deep ditch through grassy fields. Very few individuals of any other species are here but Desert Forktail is abundant.It has not yet been found at other saline sites in Nebraska.
