Host plants:
The larvae feed on Artemisia herba-alba and Artemisia barrelieri.
Habitat:
Saragossa seeboldi inhabits salty areas, steppe slopes, rocks, barrancos and generally very dry, semi-desert-like open landscapes where the larval host plants are abundant. It can occur up to more than 1400m on dry mountain slopes (e.g. northern slopes of Sierra de Baza) and occurs there in open places in partly lightly wooded slopes. On the other hand Saragossa seeboldi also lives on cpasts (e.g. Cabo de Gata, here like in the Sierra de Baza on Artemisia barrelieri).
Life cycle:
The moths occur like many other semi-desert species in autumn (September and October). Oviposition occurs in batches on the twigs of the hostplant. The mobile young larvae disperse a bit and stay on the plants also in daytime. I have beaten them numerously from Artemisia herba-alba in early October (east of Baza). The older larvae hide on or in the soil during daytime and feed at night. I could beat them also east of baza one hour after sunset in mid-November. During daytime I only found a single larva feeding during bad weather in the Sierra de Baza at about 1400m (not parasitized, Artemisia barrelieri). The larvae are mature in November and pupate in a dense but soft cocoon relatively deep in the soil until December. The pupal stage lasts then until next autumn or even longer (several years).
Remarks:
Saragossa seeboldi occurs in NW-Africa (Morocco) and in the more eastern part of Spain (from Adalucia to the Ebro valley). It is locally more widespread than formerly thought and is obviously not rare in e.g. most of southeastern Andalucia and Murcia. But many habitats have already fallen victim to vast agricultural intensification and also overbuilding. Another, more and more important endangerment factor is renewable energy (especially solar panels).
