I've managed to work through a couple of bagfuls of leaves collected on Monday, and I've ended with up with a decent number of species/records. Perhaps the most remarkable part of this is that I bumped into a smallish tree on a verge that I didn't immediately recognise, and that I'd absolutely missed/ignored earlier in the year. Anyway, I worked out it was probably a Hornbeam and I found some interesting mines on it.
The mine below is an upper surface silvery-looking blotch, similar to the ubiquitous Phyllonorycter coryli that is found on Hazel. I'd already decided that this was probably Phyllonorycter esperella if my foodplant ID was right.
