I have spent a long, long time looking for these guys which just fascinate me! Finally I found a few on some nannyberry shrubs. Since I first found one individual I have gone back many times and stared at the shrubs until my eyes feel like they are falling out, looking for these minute treehoppers. Previous photos have been terrible! Today I finally found three of these guys and managed a few shots that are reasonably OK, not great, but adequate.

To me they look they miniature dinosaurs. That big thorn-like projection is actually the pronotum which in many treehopper species has developed to cover much of the body, like a shield I guess. Many species have these thorn-like or horn-like projections. On twigs of shrubs they look like parts of the plant! You can see the head with a big dark eye under the "thorn", on the right side of the insect.
