Forewing: discoidal streak widening towards apex, notched pre-apically on the anterior margin and obliquely truncate at apex; spot beyond large, broadly triangular, well separated; discal spots in pairs varying in size, spot of this series in interspace 1 always an elongate; spots in transverse postdiscal series obscure, not all well defined, margined on both sides with deeper black than that of the ground colour; the space between the series and the discal spots and also the terminal margin beyond it with obscure transverse pale markings. Hindwing: costal margin broadly greyish brown; subbasal band not extending to the costa, of varying width; discal and subterminal pale transverse lines, the space between them darker than the ground colour, traversed by a prominent series of postdiscal spots of varying size. Cilia white alternating with black.

Rare
Under 5% of wildlife watchers report a Short Banded Sailer sighting in Guangzhou on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 188th most-seen of the 482 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.
February, April, June, September–October and December
In those months about 10% of wildlife watchers report a Short Banded Sailer in Guangzhou on a given day, against under 5% in January, March, May, July–August and November, the lowest months.
6th of 6
Of the 6 cities where we can rate Short Banded Sailer sightings, Guangzhou ranks 6th at under 5%. The best odds are in Singapore (Singapore, about 20%), Tuen Mun (China, about 10%) and Hong Kong (China, about 10%).
Same family: Nymphalidae
The closest relatives of the Short Banded Sailer that you can see in Guangzhou (family Nymphalidae, Brush-footed Butterflies) are Lemon Pansy (about 20%), Chocolate Pansy (about 20%) and Great Eggfly (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Short Banded Sailer is recorded against all the insects logged in Guangzhou (15 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.
