Sabanilla de Montes de Oca, San José, Costa Rica With the help of a special microphone, we can listen to the substrate-borne vibrations of these treehoppers. Observe the movements of the abdomen as they produce the substrate-borne vibrations to know which treehopper is "talking". Females and males of this species are distinguished by coloration. The females are yellow with a few black spots, and the males are black with the dorsal and distal tips of their pronotum in yellow. In this video, you can see a male mounting a female, and the female producing a "drumming" signal as she rejects the male. Little plastic numbers were glued to treehoppers to identify individuals as part of my research project.
