Diane took these two photos of a peculiarly shaped little bug nymph. I took a much more inferior photo, but it had enough detail that I sent it to Bug Guide for help with ID. They said it was a planthopper nymph, but didn't say which species. I am leaning towards Acanalonia, as the nymphs of the very common Metcalfa pruinosa are completely different, and this has somewhat the shape of the Acanolonia planthopper.
