Froghopper on Privet hedge
No interactions present.
I discounted it being Aphrophora alni because of the presence of the fine hairs that A. alni doesn't have.
Can't say if it is Philaenus, but definitely not Aphrophora.
Yes, the hairs and patterning make this P. spumarius. There is a weak keel on the vertex, but not a clear one running across both vertex and pronotum.
