Host plants:
The larvae feed on Tamarix species, in SW-Europe supposedly most often on T. gallica.
Habitat:
Clytie illunaris inhabits lowland habitats of all kinds provided that Tamarix occurs, e.g. especially coastal wetlands, rivers, salty inland places etc.
Life cycle:
The moths usually occur in two or three generations between April and October. The larvae mostly live between late May and November. I recorded them quite numerously in SW-Spain (province of Cadiz) in late September 2017. Some of these larvae resulted in moths in the same year. The pupa hibernates.
Remarks:
Clytie illunaris occurs in NW-Africa (and the Canaries), the Arabian Peninsula and in SW-Europe (Iberian Peninsula, France, Italy).
