It is a banded leafhopper adult in its final colorful stage. They can sometimes be numerous in the summer. I have not had any damage from them, but the spread of plant diseases is possible.

In the summer, I sometimes see tiny misting droplets looking towards the sun and emanating from my caneberries and otheer shrubs. It is coming from these insects. A spray from a hose will send dozens of them into flight.

So, they are no threat to my garden then?

Some plants with heavy infestations of leafhoppers may develop a conspicuous spotted appearance. Being an abundant sucking insect as are aphids it would seem there might also be similar potential for transmitting detrimental viruses to plants.
