Figure 1 from: Ney G, Schul J (2019) Epigenetic and genetic variation between two behaviorally isolated species of Neoconocephalus (Orthoptera: Tettigonioidea). Journal of Orthoptera Research 28(1): 11-19. https://doi.org/10.3897/jor.28.28888

Figure 1 Species assignment based on call pulse period ratio and center frequency. Labeled boxes indicate the calls classified as N.robustus and N.bivocatus. Individuals that fall outside of species classifications were removed from further epigenetic and genetic analyses (as described in Ney and Schul 2017).
