Construction of the Imago
Colored male adults of Erythrodiplax fulva have a reddish-brown abdomen , with the first two or three segments being greenish and having a brownish stripe on the top. In both sexes, the abdomen reaches an average of 15 to 16 millimeters. Young males and females have a yellowish to dark brown abdomen with wide stripes on the sides and another wide stripe on the top.
The trunk of both sexes is yellowish green on the side, the color becomes darker towards the top and takes on a brownish tinge in the females. The legs are brown and the wings are transparent with a yellowish to reddish brown spot on the base of the wing. On average, the hind wings of the females are 19.7 millimeters larger than the hind wings of the males, which measure 19.1 millimeters. With an average of 2.4 millimeters, the wing mark in the forewing is the same in both sexes.
Another sexual dimorphism is the coloring in the face area. While the males have an orange-red forehead that becomes darker towards the sides, that of the females is yellowish to yellowish green and becomes darker and greener towards the top and the sides. In both sexes, however, the clypeus and the lower lip are yellowish.
