I only ever see one and only in the Summer when I put my Orchids out and only on the one Orchid. It hops like a flea but with better accuracy, white fuzzy tail that flicks, rocks back and forth like a mantis and has red/orange eyes. The plant that I find it on doesn’t seem to be suffering any ill effects.
Your fuzzy little guy is a planthopper nymph. There is no common name for your planthopper known as Acanalonia servillei. The nymph looks similar to others in the same genus but the coloration helps to separate them. Usually nymphal ID is not possible as many look the same, but in this case I think this is the one you have. More angles are always helpful for positive Id when trying to identify from photos.
It is found in eastern US. The nymphs and adults feed on a wide variety of trees and shrubs. Not sure why you only see it on your orchid. They can be found in fields, wooded areas, gardens, and in most areas of herbaceous plants from summer into fall.
And you are right…they are not considered a pest.
