Host plants:
The caterpillars live on grasses. I found them on Bromus erectus, Arrhenaterum elatius, Festuca ovina agg. and Brachypodium pinnatum (Swabian Alb).
Habitat:
Mythimna l-album inhabits warm, dry grasslands, sunny slopes and similar, gappy vegetated habitats.
Life cycle:
The caterpillar overwinters. In the Swabian Alb, I shook it from grass clumps, for example, in February 2007 and May 2005, still quite small on a small overhang on a slope in a limestone grassland. The moths are on the wing from May to September mainly in two generations, of which the second may be only partial in the mountains.
Remarks:
Mythimna l-album is widespread in Southern Europe and extends in Central Europe approximately to the northern edge of the medium high mountains. Further north Mythimna l-album occurs only as a rare migrant. In addition, it is found from northwestern Africa to Central Asia.
