Phyllonorycter viminetorum?

After giving my son a lift this afternoon, I was close to Loughor Bridge, so I decided to have a quick 30mins botanising before the promised rain. Passing a Salix viminalis (the thin-leaved basket osier), I noticed that the edges of some leaves were curled and looking at UK Leaf Mines later, Phyllonorycter viminetorum looks a possibility? Any thoughts?

Following Sam`s comments below, I opened both up, but only could find black frass (see below):


  1. Salix mines can be tough. Can you look to see if there is a cocoon present in the mine ( Of course if it has not yet hatched, bag it up and leave it in the garden for the winter and then see what emerges in spring!

  2. I carefully looked - and only black frass.

  3. Then you are probably correct - though I'm Dave not Sam! (I must remember to sign my comments!)
