This species is similar to V. arquata, with a dark brown pronotum and bold black wing venation, but there is a third mark on the pronotum, a pale/white mid-dorsal spot; hence the name Three-spotted. Adult males are 3 to 3.5 mm long while females are 4 mm. See FSCA for more.
Nymphs are brown overall, speckled with white. |

| behavior |
To listen to the male courtship call for this genus, listen here. These courtship calls are not audible to the human ear, and the calls here are produced by recording the substrate vibrations that the treehoppers use to communicate through the plants themselves. The recorded call is then amplified so that it is now audible to human ears. Research has shown that treehoppers use vibrations to attract mates, to announce the discovery of a good feeding site, or to alert a defending mother to the approach of a predator (T.IM). |
