This is an iPhone 6 photograph of this beautifully green colored Fork-Tailed Bush Katydid, Scudderia cuneata (Orthoptera: Tettigoniidae). They are a similar species to the short-horned grasshopper and are widespread in the eastern and southeastern United States. They’re also found in California, Maine and Texas. They are native to the U.S.
They resemble grasshoppers but their rear legs are long and thin. Males have an unusual forked appendage at the end of their abdomen called a furcula. Katydids have much longer antennae than grasshoppers. They have excellent eyesight and, when startled, they can hide behind leaves very quickly. Their hosts are primarily citrus plants especially the sweet orange. They feed on the young fruit causing a circular scar in the peel and, on the leaves, they leave ragged circular holes (very noticeable on our plant). While we do not have any citrus plants directly around our house, there is a citrus tree at the house across the court from us.
