Greater arid-land predaceous Katydid - Neobarrettia spinosa
I'm assuming this is a female, as it is the biggest one I've ever seen. Found it resting on one of my tomato plants this morning. While observing and photographing it, it was curious and aware of me, but was not aggressive. I caught it in a drinking pitcher with lid, and re-located it to another part of the yard, as I don't want it eating my praying mantis.
