| description |
A grayish-brown species with a long, slender pronotal horn with a rounded tip. The horn can be mottled, with black lining the edge and white spots present on the surface. Nymphs are brownish overall, a similar color to that of the adults. There is a row of pairs of spines going down the abdomen, as well as a pair of spines in the middle of the thorax. A small forward-facing horn projects from the pronotum. |

| plant associates |
Southern red oak (Quercus falcata) (CTNC); has also been associated with American Chestnut (Castanea dentata) and black oak (Q. velutina) . Adults have additionally been found on Pyrus (pear), Quercus alba (white oak), Q. bicolor (swamp white oak), Q. coccinea (scarlet oak), Q. ilicifolia (bear or scrub oak), Q. montana (chestnut oak), Q. palustris (pin oak), Q. phellos (willow oak), Q. rubra (northern red oak), Q. stellata (post oak), and Robinia pseudoacacia (black locust) (Wallace 2014). |
| 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). |
| comments |
Can be attracted at night with a light. G. acuminatus is very closely related to Telonaca alta, with both species having almost identical nymphs (pers. comm. M.S. Wallace). Therefore, in some situations, identifications may only be tentative at best. |
