4.088 BF36a. Ectoedemia heringella (Mariani, 1939)
On 5th May 2020 Jamie O’Neill posted images on Insects & Invertebrates Ireland Facebook page of an abundant leaf miner that he found on Evergreen Oak in Phoenix Park, Dublin. He putatively identified them as E. heringella. This was quickly confirmed by Stuart Dunlop and Dave Allen (DA) who also confirmed it, after consultation with Ken Bond, as “New to Ireland”. A few weeks later Philip Strickland contacted DA with images of the same species from the same locality but taken on 13th February 2017! The mines are persistent so can be found in any month of the year. The species has obviously been established here for a number of years but remained undetected. If it follows the same pattern as in GB, where it was first found close to Kew Gardens in London, then it will certainly colonise other parts of Ireland.
