CENTRAL FLORIDA CRITTER OF THE DAY: Red-banded Leafhopper (Graphocephala coccinea)
This sharpshooter (subfamily Cicadellinae) is associated mostly with Blackberry and Raspberry. I have a lot of Rubus spp. (Blackberry). They eat the xylem: the tissue in plants that provide support (think branches) and transmits water and nutrients from the roots.
This may be subspecies, G. c. quadrivittata, an inland species (as opposed to C.g. coccinea which is coastal).
This guy (sometimes known by the common name: Candystriped Leafhopper) is shown on Florida Native Plant BLADDERPOD (Sesbania vesicaria)
