Plant Parasites of Europe

leafminers, galls and fungi

Elachista diederichsiella

Elachista diederichsiella Hering, 1889


The mine descends from just below the leaf tip. It begins as a narrow corridor, that widens abruptly into a broad, withish, strongly inflated Phyllonorycter – like blotch that is visible at both sides of the leaf. The entire mine is 2-3 cm long. Often 2-4 larvae in a mine. Frass irregularly distributed in the entire mine. Pupation external.

Milium seems to be the most important host plant (according to Hering even the only one).


Larve in April – May (Traugott-Olsen & Nielsen, 1977a).


Not known from the Benelux countries (Fauna Europaea, 2010).
