It is found in the western parts of the Palearctic ecozone, including Morocco, Europe, Turkey, the Caucasus, Israel and Lebanon. Technical description and variation{{Entomology glossary hatnote}}The wingspan is {{convert|32|to|40|mm}}. Forewing pale ochreous with slight dark dusting and a faint reddish tinge;veins finely defined by brown streaks, which are also distinct in the intervals; a diffuse brown shade below median vein; outer dots on veins 2 and 5 only; hindwing whitish ochreous, grey-tinged along middle from base, with a postmedian line of dark grey dashes on veins. Three distinct aberrations are mentioned by Tutt, all apparently British; obsoleta Tutt, a very rare pale form, with all the dots of forewing absent, the median nervure pure white, and the hindwing white without dots; in rufolinea Tutt the coloration is bright rufous, so that the forewing appears to consist of alternate fine lines of red and white; lastly in nigrostriata Tutt the coloration is blackish, the wing appearing to be a succession of black and white lines; the shade beneath median vein is almost black, and the hindwing is much darker; the majority of these darker forms are males.[1] BiologyThe moth flies from June to August depending on the location. Larva ochreous with grey freckles; lines paler edged with dark grey; subspiracular line paler.The larvae feed on Phragmites and Phalaris.[2] References1. ^Seitz, A.
