This one is a Citrus Flatid Planthopper (I had to do an ID request on BugGuide to find that out). Latin Metcalfa pruinosa. It's a nymph, and it secretes waxy filament to hide in. Why that would work on a green plant is sort of beyond me, but I've found this fellow two days in a row (on two different phlox plants) so apparently he's successfully avoiding predators. Still rather alarming to peek closely at fuzz and see eyeballs and legs. I now suspect everything in my yard of secretly being a bug!
Not the most pleasant looking bug, even as a nymph. Makes me wonder what it will look like grown up. Do you have citrus plant/trees in your yard? Great shot though.
