Plant Parasites of Europe

leafminers, galls and fungi

Elachista obliquella

Elachista obliquella Stainton, 1854

wood dwarf


Oviposition on the upperside of the leaf, often 2-3 eggs on the same leaf. Initially a narrow, brown, ascending corridor is made, with most frass in its basal part. This mine is soon vacated, and a new mine is made in another leaf. This secondary mine is an elongated, somewhat inflated blotch, as wide as the leaf.

host plants

References in the literature to Elymus repens and Sesleria albicans probably refer to E. adscitella (Traugott-Olsen & Nielsen, 1977a; Bland, 1996a); possibly this also applies to Deschampsia.
