The male of the species is 33 to 35 millimeters long and has a hindwing 24 to 27 millimeters long. It is powder blue with light brown sides and a dark tip to the abdomen. It can be distinguished from Brachydiplax farinosa by a yellow tinge to the base of the hindwing. The female is brownish yellow in color with darker markings along the dorsal abdomen. Its wings lack the yellow tinge.
This species is found in many types of wet habitat, including brackish and disturbed waters. The males are seen more often, due to their territorial behavior. Females oviposit by "flicking" an egg mass out of the water into rocks and vegetation nearby.
