clanis bilineata tsingtauica
Distribution
It is found in Asia, but see the subspecies section for a detailed range.
Description
The wingspan is 94–150 mm for ssp. bilineata and 94–120 mm for ssp. tsingtauica.
Biology
Adults of the nominate subspecies are on wing from late February until October, with peaks in April, late July-early August, and mid September in Hong Kong. There are multiple generations per year. Subspecies tsingtauica is on wing from May to late September in Korea.
Larvae of the nominate subspecies have been recorded on Pongamia pinnata, Millettia atropurpurea and Pterocarpus marsupium in India. In southern China it has been recorded from Mucuna and Pueraria. Subspecies tsingtauica is monophagous on Fabaceae in China, including Acacia, Glycine, Mucuna, Pueraria and Robinia species. Other recorded food plants include Olea and Paulownia but these are almost certainly erroneous.
Subspecies tsingtauica is a major pest of soyabeans in China, often defoliating entire fields.
Subspecies
Some authors recognise three distinct subspecies, while others regard them as synonyms:
