Cosmopterix lienigiella Zeller, 1846

fen cosmet

Cosmopterix lienigiella mine

Phragmites australis; coll Sjaak Koster


At first a gallery, but soon widened to a broad blotch, entirely or partly running upwards, in the end half as wide as the leaf. The mine is widened without consideration for the length veins, making the mine less sharply delineated than in C. scribaiella. Most frass in the first section, but higher up still some scattered frass visible. Contrary to C. scribaiella the larva does not spin a shelter for retreat in the mine; this makes the larva easily visible in the unopened mine. Cocoon in the top section of the mine. The pupa lies head-upwards, just below an opening that has been prepared as an exit for the later moth.
