Leaf Beetle Larva: Trirhabda species

Dear Maurice,
One of the easiest ways to identify a plant feeding insect is to know the plant upon which it is feeding.  This is actually a Leaf Beetle larva, and we have found a matching image on BugGuide for the genus
Trirhabda.  Of the genus, BugGuide notes:  “26 spp. in our area” and “Host plants are in the families Asteraceae and Hydrophyllaceae. Larvae and adults usually feed on leaves and flowers of a single plant species or genus: one group of species feeds on goldenrod (Solidago); another group on wormwood (Artemisia); another on Yerba Santa (Eriodictyon); etc.”
