This moth was seen frequently during a visit to the east side of Pinnacles NM...first during an evening hike, and then throughout the next day. Tentative ID [thanks to Paul Johnson] is Sericosema juturnaria (or something close to that). The caterpillar of S. juturnaria is shown here. The BugGuide info page for S. juturnaria states that its host plants are species of Ceanothus and Rhamnus. Buckbrush (Ceanothus cuneatus) and Holly-leaf Redberry (Rhamnus ilicifolia) are common shrubs in the area.

In Sericosema, females have simple antennae and males have plumose (bipectinate) antennae, with pectination almost to the base. This moth has simple is a female.
