Rare
Under 5% of wildlife watchers report a Yemma exilis sighting in Tokyo on a given day, based on 48 verified sightings from GBIF citizen-science data. It is the 243rd most-seen of the 1013 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.
June and July
In those months about 10% of wildlife watchers report a Yemma exilis in Tokyo on a given day, against under 5% in August to May, the lowest months.
4th of 4
Of the 4 cities where we can rate Yemma exilis sightings, Tokyo ranks 4th at under 5%. The best odds are in Seoul (South Korea, about 10%), Beijing (China, about 10%) and Osaka (Japan, about 10%).
Same order: Hemiptera
The closest relatives of the Yemma exilis that you can see in Tokyo (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Yellow-Spotted Stink Bug (about 30%), Large Brown Cicada (about 30%) and Brown Winged Plant Hopper (about 30%), 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 Tokyo (48 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.
