It is the third spring in a row that this bug comes and wipes out our bushes!
It is rather big (2 or 3 cm), flies heavily, and slowly lays some small black patches on the leaves (there is one in the photo), there seems to be some sticky transparent coating around these black patches . When the patches go, they leave a nice hole in the leaves of the exact same size.
They come earli-ish in spring.
