With luck
About 10% of wildlife watchers report a Japanese Broadwinged Katydid sighting in Nagoya on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 147th most-seen of the 195 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Japanese Broadwinged Katydid in Nagoya on a given day, against under 5% in December to July, the lowest months. That is one of Nagoya's wettest months, with about 220 mm of rain against 75 mm in January.
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.
Yes
Of the 4 cities where we can rate Japanese Broadwinged Katydid sightings, Nagoya has the highest daily chance: about 10%. Next come Tokyo (Japan, about 10%) and Osaka (Japan, under 5%).
Same family: Tettigoniidae
The closest relatives of the Japanese Broadwinged Katydid that you can see in Nagoya (family Tettigoniidae, Katydids) are Euconocephalus varius (about 30%), Spotted Meadow Katydid (about 20%) and Ducetia japonica (about 20%), 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 Nagoya (6 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.
