GREAT photos
Great photos and they are a great addition to BugGuide. Based on red on the first two antennal segments (scape and pedicel), with black on the proximal portion of the antennae, and red on the head – this appears to be a Western Tree Cricket. It is a female -- you can see the black ovipositor at her backend. A male would have the wings laying on the body and are paddle shaped. Presuming this is a Western Tree Cricket, it is the first photo I have seen with antennal markings. In fact, (though I am not YET an expert ) I was not even aware that O. californicus has antennal markings. I’ll send a message to Dr. Walker to see if he has more information on these antennal markings.

According to Dr. Walker
.."Yes, californicus often has a thin dark line on the inner edge of the ventral surface of the first two antennal segments."
