My camera is bright red and I was very close so this is what the leafhopper was looking at. So you can see it was now something it was used to seeing. I suspect that it might have actually seen its own reflection in the lens which might have spurred on its actions.
The common name is Broad-headed Sharpshooter and it is among the largest of the North American leafhoppers. This one was on my milkweed plant but they commonly feed on other plant sap in meadows and woodland edges. This one is a male; the females have chalky spots on their forewings called brochosomes which they scrap onto their eggs to protect them from drying in the hot July sun.
I’m not sure exactly why they are called sharpshooters but one web site suggested that it was because of their ability to quickly project themselves into the air like a bullet or because they shoot their wastes with a lot of force. It is a member of the Leafhopper (family Cicadelidae). There was very little written about them that I could find.
