With luck
About 10% of wildlife watchers report a Ducetia japonica sighting in Tokyo on a given day, based on 88 verified sightings from GBIF citizen-science data. It is the 166th most-seen of the 1013 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.
August to November
In those months about 10% of wildlife watchers report a Ducetia japonica in Tokyo on a given day, against under 5% in December to July, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ducetia japonica sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
7th of 10
Of the 10 cities where we can rate Ducetia japonica sightings, Tokyo ranks 7th at about 10%. The best odds are in Nagoya (Japan, about 20%), Sendai (Japan, about 10%) and Seoul (South Korea, about 10%).
Same family: Tettigoniidae
The closest relatives of the Ducetia japonica that you can see in Tokyo (family Tettigoniidae, Katydids) are Euconocephalus varius (about 10%), Spotted Meadow Katydid (about 10%) and Japanese Green Bush-Cricket (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ducetia japonica is recorded against all the insects logged in Tokyo (88 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.
