With luck
About 10% of wildlife watchers report a Polionemobius taprobanense sighting in Hangzhou on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 145th most-seen of the 172 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.
February, June and September–October
In those months about 10% of wildlife watchers report a Polionemobius taprobanense in Hangzhou on a given day, against under 5% in March–May, July–August and November–January, the lowest months.
Among the best
Of the 11 cities where we can rate Polionemobius taprobanense sightings, Hangzhou ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Beijing (China, about 10%), Osaka (Japan, about 10%) and Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 10%).
Same family: Trigonidiidae
The closest relatives of the Polionemobius taprobanense that you can see in Hangzhou (family Trigonidiidae, Trigs, Sword-tailed Crickets, and Ground Crickets) are Amusurgus genji (about 10%), Svistella bifasciata (about 10%) and Homoeoxipha obliterata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Polionemobius taprobanense is recorded against all the insects logged in Hangzhou (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.
