Host plants:
The larvae feed most often on Lamiaceae, especially Thymus. Literature also gives other plants such as Fabaceae.
Habitat:
Scopula submutata inhabits rocky, dry and hot places, e.g. in Mediterranean maquis.
Life cycle:
The larva hibernates. I found it in April 2013 on Thymus in Provence in April 2013. The moths occur most often in two generations (sometimes also three or just one) between mid-May and early October.
Remarks:
Scopula submutata occurs in several subspecies from NW-Africa across Southern Europe to Turkey and the Near East. In the North it is found up to South Tyrol.
Further east in Asia (from E-Turkey) closely related forms occur (Scopula transcaspica).
