This small planthopper is Catonia picta. The plant is an oleander. The genus has ten species in North America. I could not find any additional information on this hopper.

I found this bug on my black pick-up truck which is probably not the typical habitat of this planthopper. The species Catonia nava seems to be most abundant in the Southeastern US.
