A tiny, dark-coloured Elachista appeared in one of my quadrats, sampled among Eriophorum angustifolium and E. vaginatum. I need to check it with a book, but it looks rather similar to Biselachista serricornis.
Another quadrat, among Myrica, was enlivened by an Acleris flying out. This seems to be A. notana, which feeds on Bog Myrtle as well as Birch.
A few other mines, including Stigmella nylandriella on Rowan, finished the day.
