Description: The Costal Lyric cicadas can be distinguished from other Lyric cicadas by their vibrant turquoise-green colors. Its sound is like an angle grinder tool steadily grinding a slightly uneven surface.
Description: Robinson’s Cicada looks like Linne’s Cicada with less of a wing bend, and a different call. Its call is kind of like N. latifasciatus, but much more raspy.
