Planthopper (Pelitropis rotulata).
This mottled green planthopper, with its distinctive flattened head and oval crossvein pattern on the wing tips, is Pelitropis rotulata, no common name. It is native to the southeastern US (eastern Texas through Florida through Virginia) and Cuba. Nymphs have diagnostic red “tail lights”.
It’s a member of the family Tropiduchidae, and…otherwise suffers from Wikipedia Stub Syndrome. Alas!
