Sericinus is a genus of swallowtail butterflies placed in the subfamily Parnassiinae. The genus has a complex history and a multiplicity of names have been applied to its single species. Sericinus montela, the dragon swallowtail, is the only species, making the genus monotypic. It is found in the Russian Far East (south of Primorsky Krai), Korea, China and Japan.

With luck
About 10% of wildlife watchers report a Dragon Swallowtail sighting in Nanjing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 242nd most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March–April and September
In those months about 10% of wildlife watchers report a Dragon Swallowtail in Nanjing on a given day, against under 5% in May–August and October–February, the lowest months.
Among the best
Of the 4 cities where we can rate Dragon Swallowtail sightings, Nanjing ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Qingdao (China, about 10%), Beijing (China, about 10%) and Seoul (South Korea, about 10%).
Same family: Papilionidae
The closest relatives of the Dragon Swallowtail that you can see in Nanjing (family Papilionidae, Swallowtails and Parnassians) are Common Bluebottle (about 30%), Chinese Yellow Swallowtail (about 20%) and Common Rose Swallowtail (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dragon Swallowtail is recorded against all the insects logged in Nanjing (5 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.
