Springtime Darner (Basiaeschna janata ) has blue spots on the abdomen and lacks two pale yellow spots on the side of the thorax. Harlequin (Gomphaeshna furcillata ) and Taper-tailed (G. antilope ) Darner also both have blue spots on the abdomen and lateral thoracic stripes rather than spots.

This species could be considered crepuscular, with its chief activity occurring well into the evening. One study reported that it often competes with bats for prey around lake edges. It is not uncommon, however, to see males patrolling along shaded areas of streams or lake shores earlier in the day. Fawn Darner has been called the most abundant and widely distributed river dragonfly in the Great Plains. I have found them so abundant in some areas as to be overflowing collection heads of a malaise trap. Williamson also commented on the discriminating nature of this dragonfly's feeding; occasionally rejecting some prey after seizing it.
