Species Guides

1

Gandaritis is a of geometrid moths comprising approximately 22 , with 16 species recorded from China. The genus was established by Frederic Moore in 1868. Species within this genus are primarily distributed across the Palearctic region, with notable diversity in montane areas of western China. The Barred Straw (G. pyraliata) is the best-studied species, having been sequenced for genomic analysis.

Identification

-level identification within Gandaritis relies on wing pattern differences, particularly maculation and ground color, and requires examination of male and female genitalia . Secondary sexual characteristics are absent in this . (COI) has been used to distinguish closely related species, with interspecific genetic distances ranging from 2.11% to 5.30% between tested species pairs.

Habitat

occupy montane regions at elevations from 1062 m to 3000 m in western China (Sichuan, Shaanxi, Gansu). G. pyraliata occurs in herbaceous vegetation across Europe and Asia, including Britain as far north as Orkney.

Distribution

Widely distributed across the Palearctic region. Documented from China (Sichuan, Shaanxi, Gansu provinces), Europe including Scandinavia (Denmark, Norway, Sweden), and Asia. GBIF records confirm presence in northern Europe.

Seasonality

G. pyraliata are on the wing from June to August in southern Britain. Larvae develop from April to June. overwinter.

Diet

Larvae of G. pyraliata feed primarily on Galium aparine (cleavers). plants for other in the are not documented.

Host Associations

  • Galium aparine - larval food plantprimary for G. pyraliata

Life Cycle

G. pyraliata: overwinter; larval development occurs April to June; June to August in southern Britain. details for other are not documented.

Behavior

G. pyraliata rests with wings outstretched and held aloft at an angle above horizontal, with hindwings rotated forward under forewings and the trailing edge curled. This posture renders only one pair of wings visible and may reduce detection by visual in herbaceous vegetation.
