ID needed for this larva, please

Observation - ID needed for this larva, please - UK and Ireland. Description: There are several of these larvae munching mainly raspberry leaves but I think there were a couple on tayberry and blackberry leaves too. I don't think they're bristly enough to be raspberry sawflies so could someone help with an identification please?
