2.1. Nahrung der Raupe

Streng genommen noch unbekannt, aber Bidzilya et al. (2017) fanden einen klaren Hinweis: "The trophic specialization and phenology of this species were studied in details in 2014 when the species was observed in numbers on the south bank of Barakol Lake (Fig. 37) (Budashkin 2014b). The adult flight season is uninterrupted from late May to late August in two generations. The species is restricted to Artemisia santonica (Asteraceae) plant communities in halophytic steppes. The adults were regularly observed exclusively on this plant, particularly in localities where A. santonica forms most of the vegetation cover. In spite of the fact that the immature stages have not been observed, there is no doubt that A. santonica is a host plant for S. acipenserella."
