With luck
About 10% of wildlife watchers report a Japanese Broadwinged Katydid sighting in Tokyo on a given day, based on 74 verified sightings from GBIF citizen-science data. It is the 180th 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.
May–June and August–November
In those months about 10% of wildlife watchers report a Japanese Broadwinged Katydid in Tokyo on a given day, against under 5% in July and December–April, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Japanese Broadwinged Katydid sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Japanese Broadwinged Katydid sightings, Tokyo ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%).
Same family: Tettigoniidae
The closest relatives of the Japanese Broadwinged Katydid 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 Japanese Broadwinged Katydid is recorded against all the insects logged in Tokyo (74 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.
