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.
