On my way from school drop-off to Abergavenny I paused briefly to record mines near Llanfihangel Crucorney. As well as more Stigmella atricapitella and some Ectoedemia subbimaculella (see last week's post) I was pleased to spot mines of E. occultella with their distinctive central spots on Birch. This is only the 6th county record.
