Larval development only above temperatures higher as 10°C. Hibernation as egg and later it pupates in a very narrow whitish cocoon.
Usually around six generations a year in Mediterranean regions, but it appear usually from April till October with the generations overlapping each other. In our country usually on the wing from late June towards October.
The rosy white larva develops usually in potato tubers, but when it emerges on leaves, it forms a gallery and penetrates the fruits, stems and leaves of Lycium europaeum, Lycopersicon esculentum, Nicotinia tabacum and different species of Solanum.
