Thermal image of treehoppers on a host plant

A Linear Resonant Actuator (white disc) plays songs to a treehopper on a host plant. An accelerometer (blue wires) records signals the treehopper produces. (Image: N Leith)

We track individual Enchenopa treehoppers by painting their pronota with unique color combinations of non-toxic paint. Doing so allows us to determine how consistently individuals behavior across temperatures or other environmental contexts (image: N Leith)
