Ectoedemia albifasciella mine on oak. A couple of these on the trees; also a couple of 'green island'-forming Ectoedemias, but the mines were not far enough progressed to identify them.
Coleophora milvipennella(?) case on birch - can anyone confirm the ID? I did not look at it too closely as I thought it was the common Coleophora serratella, forgetting that the larval case of this species does not look like this in the autumn.
