There’s a local park I don’t often visit as it’s a bit too managed for my liking but, recently, when I didn’t have time for a longer walk, I headed in that direction. And I’m very glad I did as, during one 30-minute period of fossicking through fallen Oak leaves, I found three new leafminers, all feeding in the ‘green islands’ their own chemicals had induced in the leaves. This is the first, Ectoedemia heringi, distinguishable from a similar species Ectoedemia albifasciella by the brown head seen here on the larva in the mine. You can read more about this species on the British Leafminers website and see the very attractive adult moth on the UK Moths website.
