One of 30 Nearctic species
Mature males have the thorax almost completely blue, with only very thin black lines. Segments 8, 9, and 10 are all blue.
Identifying female dancers are tricky, and this species has both a blue form female and a brown form female. See Lam, page 44(1)
for good illustrations of the females.
From the U.S. Great Plains east, and from Florida through Texas and New Mexico, and on into Mexico. Ontario is the only province of Canada to have reported this species.
Blue-form female of Powdered Dancer, Argia moesta
, is very similar.
