Nach GORBUNOV (2020: 563) lebt die Raupe fast monophag an Oxytropis floribunda und wahrscheinlich noch Astragalus wolgensis: "The larval host is Astragalus longipetalus Chater (Fabaceae) (Fig. 37). However, in the Orenburg Region, males of the type series were collected in a biotope where this species of astragals was absent, but A. wolgensis Bunge was present (Fig. 38). With a high degree of probability, this astragalus is also a host plant of this new species. The larva lives in the root where it bores a tunnel about 7–9 cm long. Its life cycle is annual."
GORBUNOV (2020: 564) erläutert seine Namenswahl: "This new species is named in honour of Peter Simon Pallas (1741–1811), a Prussian natural philosopher, an academician of Saint Petersburg Academy of Sciences, who led en expedition (1769–1770) to the southern provinces of the Russian Empire, where this new species occurs."
GORBUNOV (2020: 563) schreibt zur Verbreitung: "The new species is known from a few localities in the southeastern European part of Russia (Orenburg Region) and northwestern part of Kazakhstan (Aktyubinsk Region)."
