Norway maples....Phyllonorycter joannisi

I had the opportunity for a short episode of leaf-mining this afternoon (10/9), so I deliberately targeted a stand of planted Norway maples alongside the A484 at Penallt, Llanelli.
One tree had an abundance of vacated Phyllonorycter blisters under the leaves which seem to be P. joannisi according to UK Leaf Mines. Apparently this species is rapidly spreading northwards and westwards in the UK.
