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
. Buckbrush (Ceanothus cuneatus
) and Holly-leaf Redberry (Rhamnus ilicifolia
) are common shrubs in the area.
, females have simple antennae and males have plumose (bipectinate) antennae, with pectination almost to the base. This moth has simple antenna...so is a female.
