Magicicada septendecula Alexander and Moore 1962
Usually smaller than M. septendecim and similar to M. cassini in size, with narrow, well-defined orange stripes on the underside of the abdomen but no orange coloration in front of the wing insertion behind the eye. This species is often much more rare than M. septendecim and M. cassini. The calling song of the -decula sibling species is rhythmically unlike those of the other two forms, and consists of a series of short phrases lasting 15-30 seconds. The first two courtship songs have not been well characterized, but may bear the same relationship to each other as the courtship songs of the other species. Scale below is 1 cm long.
