 Hi
Can anyone help me to identify this mine of Rubus saxatilis?

Thanks for help.

 Several leaves are turning colors without evidence of mining so I'm not sure you have mines. Blotch mines in Rubus in Europe are described here: https://bladminee...eae/rubus/.

 I'm inclined to agree with John. Unless you can see evidence of frass within the blotch, I would suggest this is a fungal problem - particularly the way it's affecting the very edge of the leaf.
