Old Highway west of White Rock Road at about 1800 feet in the Sierra foothills, Mariposa County, California, USA

Seen in the same area and at the same time as:
Directly under caterpillar phacelia, Phacelia cicutaria, momentarily perched on a dry stem on the ground. Comparing the smaller antennae with the other image I presume this is a female and the other a male. Also I can only see 6 abdominal segments.
