Animal communication systems evolved in order to enable individuals to behave based upon others. Cricket acoustic communication is a good model for evolutionary analysis being composed of genetically stereotyped rhythmic pulse intervals. This system represents one of the most complicated invertebrate acoustical systems, with songs evolving in very different directions in terms of speed, structure and sound properties. We aim to continue the description that has been done previously, of the singing network in G. bimaculatus and extend this characterization to other cricket species which show very different songs (G.assimilis, G. rubens and Teleogryllus oceanicus). This will be fundamental to understand where sexual selection altered the cricket singing CPG to produce the myriads of songs observed in nature.
