Coyote Brush Leaf Beetle

Trirhabda flavolimbata, also called the coyote brush leaf beetle, is a species of skeletonizing leaf beetle in the family Chrysomelidae. It is found in California in coastal scrublands or chaparral habitats. Its main host plant is coyote brush, but it has been noted to feed on other species of Baccharis, as well as Aster, Senecio, Artemisia, Solidago, and Eriodictyon.

Larvae and adult coyote brush leaf beetles are metallic green. This coloration might function as a warning color, as both larvae and adult beetles are toxic due to chemicals ingested from the coyote brush.
