This is much better than a Katydid nymph. It is a predatory Assassin Bug nymph, and we identified it as a Leafhopper Assassin Bug nymph, Zelus renardii, thanks to these images posted to BugGuide. According to BugGuide: “Generalist predator (despite its common name suggesting host specificity).” It is also pictured on the Natural History of Orange County site.
