About Phtheochroa inopiana (Haworth, 1811)
Phtheochroa inopiana, commonly known as the plain conch, is a moth species that belongs to the Tortricidae family. It can be found in Beijing, Gansu, Hebei, Heilongjiang, and Jilin in China, as well as in Iran, Japan, Mongolia, Russia, most of Europe, and it has also been recorded in North America. This species inhabits damp areas and woodland edges. The wingspan of adult Phtheochroa inopiana is 17–22 mm. Its forewings are relatively narrow, brownish in tone, and show quite a bit of variation in colour. Adults of this species exhibit sexual dimorphism, with females having plainer colouration than males. Meyrick provided the following description of the species: "Forewings light ochreous, more or less sprinkled or strigulated with brownish, sometimes reddish-tinged; sometimes two darker dots in disc beyond middle. Hindwings pale fuscous. The larva ochreous-whitish; head and plate of 2 brown." In western Europe, adult plain conchs fly from June to August. The larvae feed inside the roots of Pulicaria dysenterica, and the species overwinters in the larval stage.
