Phaneroptera falcata
In 3 days ~40% in a week ~60%
Phaneroptera falcata, the sickle-bearing bush-cricket, is a species of orthopteran belonging to the subfamily Phaneropterinae. It is mostly herbivorous and commonly measures 24 to 36 mm long. It lives mainly in warm scrub and grasslands areas, also on dry shrubbery and in sand pits and gardens.
Phaneroptera falcata occurs in Europe and has historically been restricted to southern and central parts of the continent. They are absent in the Alpine foothills and in many parts of the Swabian Alps. Phaneroptera falcata has been extending the northern limits of its range in mainland Europe in recent decades; it is now regular in parts of southernmost Scandinavia, despite only spreading to the region quite recently (first record in Denmark in 2010 and in Sweden in 2014). Vagrant adults are occasionally found in Britain, and a small, but apparently established, colony was discovered near Dungeness in Kent in 2015.

With luck
About 10% of wildlife watchers report a Sickle-Bearing Bush-Cricket sighting in Nagoya on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 104th most-seen of the 195 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Sickle-Bearing Bush-Cricket in Nagoya on a given day, against under 5% in August and October–April, the lowest months. That is one of Nagoya's wettest months, with about 220 mm of rain against 75 mm in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Sickle-Bearing Bush-Cricket sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 15
Of the 15 cities where we can rate Sickle-Bearing Bush-Cricket sightings, Nagoya ranks 2nd at about 10%. The best odds are in Daegu (South Korea, about 20%).
Same family: Tettigoniidae
The closest relatives of the Sickle-Bearing Bush-Cricket 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 Sickle-Bearing Bush-Cricket is recorded against all the insects logged in Nagoya (9 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.
