Monochroa arundinetella (Stainton, 1858)

sedge neb

mine

Rather narrow, long, corridor, of which the course largely is dictated by the venation; the mine may change direction (up/down). The larva may leave its mine and restart elsewhere. Pupation within the mine; pupa in a white cocoon, just above the waterline.

Tabell (2008a) describes how the mines are made in the underside of the outer leaves, and that the descend to below the water level.

host plants

Cyperaceae, monophagous

Carex acutiformis, riparia, rostrata.

Hering (1957a) and older authors also mention Phragmites australis; this is not repeated by later authors, and probably stems from confusion with other species.
