Clanis bilineata, the two-lined velvet hawkmoth, is a species of moth in the family Sphingidae first described by Francis Walker in 1866. It is found in Asia, but see the subspecies section for a detailed range. 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 C. b. 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. Some authors recognise three distinct subspecies, while others regard them as synonyms:
Clanis bilineata bilineata (southern India, then from Nepal and northern India (Sikkim) across southern China to Taiwan) Clanis bilineata formosana (Taiwan) Clanis bilineata tsingtauica (the Russian Far East, Japan, Korea and north-eastern China, as far... Wikipedia →

Rare
Under 5% of wildlife watchers report a Clanis bilineata sighting in Bengaluru on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 257th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March, May and July–September
In those months about 10% of wildlife watchers report a Clanis bilineata in Bengaluru on a given day, against under 5% in April, June and October–February, the lowest months.
2nd of 5
Of the 5 cities where we can rate Clanis bilineata sightings, Bengaluru ranks 2nd at under 5%. The best odds are in Seoul (South Korea, about 10%).
Same family: Sphingidae
The closest relatives of the Clanis bilineata that you can see in Bengaluru (family Sphingidae, Sphinx Moths) are Oleander Hawkmoth (about 20%), Plain Grey Hawkmoth (about 10%) and Convolvulus Hawkmoth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Clanis bilineata is recorded against all the insects logged in Bengaluru (12 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
