Pterochroza ocellata, the peacock katydid, is an insect in the family Tettigoniidae. The species is a leaf-mimic katydid; when it is in repose its camouflage resembles a diseased or dead leaf. The katydid owes both its common name and its specific epithet (ocellata, meaning "marked with little eyes") to its startle display, in which it shows false eye spots on its normally hidden hind wings.
