Clanis undulosa

Clanis undulosa, the wavy velvet hawkmoth, is a moth of the family Sphingidae first described by Frederic Moore in 1879. The nominate subspecies is found in the southern Russian Far East, the Korean Peninsula and north-eastern China, as far as south and west as Shaanxi and Hebei. South from Sichuan (Baoxing), Hubei, Jiangxi (Guling) and Zhejiang (Tianmu Shan), it is replaced by ssp. gigantea, which ranges west to Nepal and south, through Thailand and Vietnam, to Peninsular Malaysia.

Description
The wingspan is 100–120 mm for subspecies C. u. undulosa and 118–160 mm for subspecies C. u. gigantea. Adults of the nominate subspecies are on wing from June to early August in Korea.

Biology
The food plants of the nominate subspecies are unknown. The larvae of subspecies C. u. gigantea have been recorded on Lespedeza viatorum in Guangdong and on Lespedeza thompsoni in north-eastern India.
