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!)

  4. I just not understand anything from the written work. But trying to learn from the photos but that was not enough for me and also for my learning. So now here is a kind of different way from which we can top british essays learn and also get some of the things which is good for my learning.
