L. in N of Drakensberg. C. draconicus distinguished from clear-winged C. fasciatus by its finelymarked, yellow 'V' on thorax, and fine yellow spots between wing bases (green, brown, black with pruinescence in C. fasciatus). C. draconicus has a fine, dorsal yellow line along abdomen, which C. fasciatus does not. These two species can be confused, so it is essential to compare appendages. The superior appendages in side view are almost straight in C. draconicus but distinctly downcurved in C. fasciatus.
