Sometimes the best cicada locations are just a short distance from your home. This summer I came across a grove of pine trees that had two species of Neotibicen: Neotibicen linnei (Linne’s Cicada) and Neotibicen canicularis (Dog-Day Cicada). Neotibicen linnei and Neotibicen canicularis look very similar when they’re adults (appearances vary by location), so it helpful to compare the two species.
This image compares Neotibicen linnei and canicularis when they’ve recently molted (teneral). Note that the N. linnei is yellow and green, while the N. canicularis is a pink/salmon color.
This image compares these cicadas approximately 24 hours after molting. Note that they’ve achieved there adult coloring, which is very similar, but you can see vestiges of the pink on the N. canicularis.
This last image compares the wing shape of N. linnei (foreground) and N. canicularis (background). Both cicadas are standing on the same piece of white paper. The wings of the N. linnei have a sharper bend — see how the tip of the wing is lifted far off the surface of the paper, while the wing of the N. canicularis almost sits on the paper. Also note that the N. linnei is a more vibrant green, and the N. canicularis is more of a drab/olive green.
Read this journal article, to learn how closely these cicadas are related genetically:
