The description of the larva is based on an ex ovo rearing. Females laid eggs mainly on Dryas octopetala. Larvae were, however, fed on several plants, not only those of Rosaceae. Photographs of the larva as well as drawings of the mouthparts and chaetotaxy are shown. Egg and pupa are briefly described. According to the larval characters, the species shows resemblance to the X. speciosa group. Habitat and rearing experience are described in comparison with some other Xestia species occurring in the area.
