This is a very young, recently hatched leafhopper nymph, probably of the genus homalodisca. An older nymph and an adult are pictured in this previous post. As stated there, the species is likely to be h. coagulata, the glassy-winged sharpshooter. This strangely appealing little guy has a body the color of school paste that's been squished around in a kindergartner's dirty hand.
I'd have to assume this hopper is using the plant its on, basil, as a food source. They don't call 'em leafhoppers for nothing: this little one hopped from leaf to leaf, plant to plant a lot more quickly and farther per bound than you might expect. What is warp speed for a day-old leafhopper?
