UKMoths Please note that the NBN Gateway map service has been terminated as of 1 April 2017.
As soon as a replacement map service is available, distribution maps will hopefully appear here again.
In the meantime, you can get some idea of distribution from the NBN Atlas website.
4.09 BF38
Ectoedemia subbimaculella
(Haworth, 1828)
Wingspan 5-6 mm.
Commonest in south-east England, the distribution expands north and westwards, though the exact distribution is unclear because of earlier confusion with similar species.
The larvae mine oak (Quercus) leaves, initially in a gallery following a vein, then creating a triangular blotch between vein and midrib. It can be distinguished from the similar mines of E. heringi by the presence of a slit in the lower epidermis which allows frass and water to pass.
The adults are similar to E. heringi, but otherwise quite distinctive, with two creamy spots and a creamy basal patch on a violet-tinged blackish forewing.
