Ectoedemia argyropeza - Distribution map
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.

Ectoedemia argyropeza
(Zeller, 1839)
Wingspan c. 7mm.
Locally distributed throughout mainland Britain, though more plentiful in the south, E. argyropeza mines the leaves of aspen (Populus tremula), forming a triangular blotch extending from the midrib. When the leaves change colour in autumn, the mined area often remains a 'green island' even after the leaves have fallen.
There is a single generation, and the adults are on the wing in May and June. It is believed to be parthenogenetic over most of its UK range.
