The juvenile has a white face, red-brown eyes, brown shoulders, a grayish thorax, and a yellow abdomen with a black dorsal stripe. Each wing is marked with black: a streak at base, a small spot in middle, a black stigma (near the tip), and a black tip. In the females, the black tips extend to the stigmas. The eyes are blue at maturity. The abdomen is brown in mature females. The front of the thorax becomes blue and then the abdomen for the males at maturity. The body length varies from 2.2 to 2.5 inches. The juveniles and females are similar to those of the slaty skimmer.
