Saturnia (Eriogyna) Comparison Chart

I have created this comparison chart with notes to help determine the Asian Saturnia (Eriogyna) group, based on information from the publication cited top of page.

Saturnia cameronensis male, endemic to Cameron Highlands, Malaysia.

wingspan: 90mm; elevations of 1200-1600m; basal dark area is relatively small; am line is dark, inwardly lined with red, concave from the inner margin to vein Cu1 where there is a distinct angulation; the first of the double pm lines is distinct, perpendicular to the inner margin and divides the lower portion of the white region in half; the forewing eyespots are relatively large.

The upper "teeth" of the inner pm line project over the eyespot.

Saturnia centralis male, (forewing length: males: 41-49mm; females: 48-55) flies in China: Yunnan, Sichuan; Myanmar (Burma): Tangpengshan, Xingwei (East Myanmar) and northern Thailand: Provinz Chiang Mai; at altitudes from 2400m - 4000m (2000m in Thailand).
am line is dark, inwardly lined with red, concave from the inner margin to the costa; double pm lines are distinct, perpendicular to i m and divide the lower portion of white region in half; forewing eyespots are smaller and the forewing is more elongate/falcate compared to S. cameronensis.

Saturnia cidosa male, (forewing length: males: estimated 37-45mm; females: estimated 44-50mm) flies in northeastern India, Sikkam and Nepal. It seems endemic to those areas.

Note the lunulate hindwing postmedian band. This species is smaller than S. centralis, and the forewing outer margin is not as oblique.

Note the projection of the pm "teeth" over the relatively large eyspot. The dark postmedian area is wider than in other species.

Saturnia cognata male, (wingspan: males: 71-77mm; females: 97mm) flies in China: Guangxi, Shaanxi, Fujian, Jianxi, Guizhou, Hunan, Hubei, Shaanxi, Sichuan, Yunnan, Beijing; and probably as far north as South Korea in the winter (October-December-March).

basal area is dark; am and pm lines converge at inner margin; double pm lines are close together with little white scaling between them; much white in submarginal areas of all wings

Sorry, no image available at this time.

Saturnia luctifera flies in China: Sichuan and Shaanxi. It is a small, dark species that flies in the summer months. It was previously treated as a subspecies of Saturnia pyretorum and has a similar appearance.

Saturnia pyretorum male, flies in Taiwan, northern Vietnam and southern China: Fujian, Jiangxi, Guangdong, Hainan, Hunan, Sichuan, Yunnan.

slightly larger than S. cognata, with larger eyespots; basal area is dark; am and pm lines converge at inner margin; double pm lines are close together with little white scaling between them; submarginal white bands not as wide as in S. cognata.

Saturnia pinratanai male, (wingspan: males: 66mm; females: 108mm) flies in Doi Inthanon northern Thailand at elevations near 1700m. According to Stefan Naumann, reports of this species from southern Thailand are in error.

The male is well distinguished from pyretorum and cameronensis by the falcate apex of forewings, and by the strongly darkened coloration of wings and antennae.

The hindwing eyespots are small and dark.

The status of the other S. pyretorum subspecies remains unclear.

N pyretorum fusca Watson, 1915 (“1914”) China with unclear status
N pyretorum roseata De Joannis, 1929 northern Vietnam with unclear status; might be pyretorum
N pyretorum tonkinensis Bouvier, 1936 northern Vietnam with unclear status; might be pyretorum or pyretorum roseata
