I suspect that this damage on wild raspberry (Rubus ideaus) has been caused by a virus. Is an ID possible?
No identification made yet.
No interactions present.
Probably insect damage, perhaps by leaf-beetle larvae, sawfly larvae, caterpillars or many of the blotch-mine creator community, sorry not more specific,
That was my first thought but a search has turned up nothing that seems to cause damage like this. Some pictures of what is claimed to be viral damage, from some unspecified virus, are the best fit I've seen so far. Happy, though, to be proved wrong.
