[N] Thetidia plusiaria: Habitat near Teruel in the Sierra de Javalambre in late July 2013 [N]

Host plants:
The larvae especially feed on Santolina chamaecyparissus, but are also said to live on Artemisia sp.

Habitat:
Thetidia plusiaria inhabits open, dry and warm places such as extensively grazed mountain slopes.

Life cycle:
The moths occur according to literature mostly in two generations in june and July and again in September. I observed many fresh specimens in eastern Spain (Teruel and CastellÚn) in 1000 and 1700m asl in late July 2013 and think that there might be only one major generation in these habitats.

The adults most often rest within the shrubs of their host plant.

Remarks:
Thetidia plusiaria occurs in NW-Africa and Spain, locally also in the French east Pyrenees.
