Finishing off Holm Oak

Below are upper and underside views of the blotch mine caused by Phyllonorycter messaniella on Holm Oak. At this time of year the underside 'skin' of the leaf mine is often torn but it should still be recognisable.
If the mine is intact, note the crease which is a feature of many Phyllonorycter mines.
