Length: typically 5.0 - 6.5 mm
In genus Eutettix, the scutellum has a large, dark spot next to each of the two basal angles, and a pair of smaller spots between the larger ones. The scutellar suture is slightly darkened. As with so many leafhopper groups, though, confident identification is based on the internal male genitalia.
Hepner (1942) reported that "apparently all members of this genus feed on various species of Oaks."
This genus is mostly a southern one, with many species found in states like Florida and Arizona.
