This is another smaller uncommon species west of the Mississippi River that is only known from Louisiana within the region. Males become bright red, including wing veins. There is a small basal amber or black spot in the hindwing. The face, thorax and pale abdominal markings are yellow in younger individuals but become red with age. The wide, black humeral stripe and third lateral stripe are not connected. The midlateral thoracic stripe is broad and fully developed below the spiracle. The face, thorax and wing veins remain yellow in females. The abdomen is slender and mostly black with pale basal markings laterally. There are pale dorsal spots present on segments 3-7.


Total length: 26-37 mm; abdomen: 16-23 mm; hindwing: 23-28 mm.

Similar Species

This species can be distinguished from other small pennants by its thoracic markings, red veins in mature males, and relative absence of markings in the hindwing. The lateral thoracic markings in Faded Pennant (C. ornata ) are connected dorsally and the hindwing spot is larger. Female and young male Seaside Dragonlets (Erythrodiplax berenice ) have an entirely black thorax or it is pale with numerous black stripes.

This species was erroneously reported from the Jones State Forest in Montgomery County, Texas. The species was actually Faded Pennant (R. Orr pers. comm.). Red-veined Pennant does not appear to range as far west as the Piney Woods of east Texas. This species is similar to Amandab?s Pennant (C. amanda ) in its habits and behavior. Females lay eggs accompanied by males and it has been noted that this species has an apparent prefrence for pine trees as roosting sites.
