Host plants:
The larvae are polyphagous on grasses and various herbs.
Habitat:
Polymixis flavicincta inhabits warm and dry terrain as for example rocky grasslands or bushy hillsides.
Life cycle:
The egg overwinters. The caterpillar lives in the spring until June. The pupa aestivates and dismisses the adult from late August or early September. The flight time lasts until October.
Endangerment: strongly endangered
Endangerment factors:
In Germany Polymixis flavicincta is threatened by extinction due to the loss of large, suitable habitats. In Baden-Württemberg, it has already disappeared. The extent in which also natural fluctuations are involved in the border area of the distribution, must remain open. In Germany it still occurs for example in the Middle Rhine/Nahe region.
Remarks:
The overall distribution ranges from Northwest Africa across western and Central Europe (including southern England) sporadically to the Black Sea. In Europe the distribution is densest in the southwest.
