With luck
About 10% of wildlife watchers report a Yemma exilis sighting in Beijing on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 107th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April, June–September and December
In those months about 10% of wildlife watchers report a Yemma exilis in Beijing on a given day, against under 5% in January–March, May and October–November, the lowest months. Those are among Beijing's wettest months, with about 70 mm of rain a month against almost none in January.
Among the best
Of the 4 cities where we can rate Yemma exilis sightings, Beijing ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Seoul (South Korea, about 10%).
Same order: Hemiptera
The closest relatives of the Yemma exilis that you can see in Beijing (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Spotted Lanternfly (about 30%), Panaorus csikii (about 20%) and Brown Marmorated Stink Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yemma exilis is recorded against all the insects logged in Beijing (29 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.
