Host plants:
The larvae feed on the flowers of a few not related plant families, so especially the Lamiaceae (Teucrium sp., in Central Europe T. chamaedrys is the main host plant; Lavandula, Salvia, Satureja thymbra) and Ericaceae (Erica manipuliflora in Samos Island, D.Fritsch). Further research is required.
Habitat:
Nola subchlamydula inhabits places with host plants. These are usually dry and warm sites like edges in dry grasslands, embankments, garigues, rocky slopes, open scrub.
Life cycle:
The pupa hibernates. In Central Europe, the moths usually occur in one generation in spring, but in the South in up to three generations (according to region) between March and October. Flight times are dependent on the availability of the regional used host plants. Additionally following generations are usually not complete. Thus phenology is quite complex.
In Central Europe, larvae are most often found in June or still early July, but in the South from April to autumn. I recorded the larvae quite common on flowering Satureja thymbra in Samos Island in mid-May 2017.
Remarks:
In Central Europe Nola subchlamydula occurs only locally and rarely in warm places (e.g. Kaiserstuhl in SW-Germany). But it is a quite common species from NW-Africa across many parts of Southern Europe to W-Asia (Turkey).
