Plastingia naga, the chequered lancer or silver-spot lancer, is a butterfly belonging to the family Hesperiidae and sub-family Hesperiinae. It has a wingspan between 33–38 mm. The underside markings of the chequered lancer consist of black veins and black rectangular spots on a greyish-white ground colour. The upperside has yellow-orange streaks at the wing bases. The upperside forewing of the male is dark brown with white hyaline (glass-like) spots, including two cell spots, at the cell-end and above the discal spot in space 2. There are also other spots in spaces 3, 6, and 7 as well as a non-hyaline streak in space 1b. The hindwing has an obscure, pale yellow cell streak and inter-neural streaks. Females are generally larger in size, darker and have less spots than the male. The spots in space 7 and the lower cell spot on the forewing may be absent. The abdomen of the chequered lancer is striped black and white, whilst the antenna has a whitish band just after the club.
The chequered lancer has a wide distribution. It can be found from Assam to Myanmar, Thailand, Laos, Malaysia, Singapore, Borneo, Indonesia, and the Philippines. The... Wikipedia →

With luck
About 10% of wildlife watchers report a Chequered Lancer sighting in Singapore on a given day, based on 83 verified sightings from GBIF citizen-science data. It is the 259th most-seen of the 1045 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.
October and December–June
In those months about 10% of wildlife watchers report a Chequered Lancer in Singapore on a given day, against under 5% in July–September and November, the lowest months.
Among the best
Of the 2 cities where we can rate Chequered Lancer sightings, Singapore ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Kuala Lumpur (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Chequered Lancer is recorded against all the insects logged in Singapore (83 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.
