I have been looking for treehoppers closely affiliated with oak trees for a long, long time. Every year I peer hopefully at the oaks, looking along twigs and under leaves, but nothing. Today, in the pouring rain, I finally found one of the oak-specific hoppers. This one has two green stripes, not particularly easy to see with the raindrops on it. Needless to say I was thrilled, and will be back on a sunnier day, hoping to see one again.
