This glorious little yellow leafhopper, with its brown and white spots, was all of 4mm long, and sitting on the leaf of a sunflower (you can just see the little hairs on the leaf’s surface in the photo), waving gently back and forth in the wind. This did not make it easy to get a macro photograph!
This is another species sadly suffering from Wikipedia Stub Syndrome. Bugguide says they live on carrot plants and little flowering shrubs in the genus Volkameria (clearly, they also at least occasionally visit sunflowers). They range all over the southern US (from Georgia/Florida to Texas) and down into the Caribbean and South America.
