About Hypercallia citrinalis (Scopoli, 1763)
Hypercallia citrinalis is a moth species that belongs to the family Depressariidae. Its distribution range covers Europe, Asia Minor, Georgia, Armenia, Azerbaijan, Mongolia, and southern Siberia, specifically the regions of Altai, Minusinsk, and Irkutsk. Adults have a wingspan of approximately 19 millimeters. The forewings are bright yellow, with specific markings that are bright crimson: a streak along the basal third of the costa with two oblique projections, a slender fascia running from the middle of the costa to one-third of the dorsum, connected by two downward-oblique bars to an irregular, interrupted subterminal fascia, as well as the second discal stigma and a narrow terminal fascia. The hindwings are grey. Full-grown larvae are greenish-grey, with a whitish dorsal line, and black dots surrounded by whitish rings. The head and second segment are speckled with black. Adult moths fly during the months of June to July, with flight timing varying by location. Larvae of this species feed on the plants Polygala vulgaris and Polygala calcarea.
