Colorado Three-lined Leaf Beetle
A small, elongated beetle with an orange-yellow body and three dark longitudinal stripes on the elytra. It feeds on tomatillo and ground cherry in the western United States.
Did You Know?
Like other Lema species, the larvae cover themselves in their own frass, which may serve both as camouflage and as a deterrent to parasitoids.
