Carex flacca, Belgium, prov. Namur, Lives-sur-Meuse © Jean-Yves Baugnée


Egg generally at the underside of the leaf tip. From September till the following spring a narrow meandering corridor is made. Then gradually the corridor widens to nearly the full width of the leaf. Generally the larvae make a new mine in early winter, obviously without the initial corridor. The mine in this stage is brown and situated close to (or within) the red coloured dying apical part of the leaf. Frass in large elongate dark spots. Pupation external.
