Phaneroptera falcata
In 3 days ~10% in a week ~30%
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 Tokyo on a given day, based on 71 verified sightings from GBIF citizen-science data. It is the 189th 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–July and September–November
In those months about 10% of wildlife watchers report a Sickle-Bearing Bush-Cricket in Tokyo on a given day, against under 5% in August and December–May, the lowest months.
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.
8th of 15
Of the 15 cities where we can rate Sickle-Bearing Bush-Cricket sightings, Tokyo ranks 8th at about 10%. The best odds are in Daegu (South Korea, about 20%), Nagoya (Japan, about 10%) and Seoul (South Korea, about 10%).
GBIF citizen-science records
It is estimated from how often the Sickle-Bearing Bush-Cricket is recorded against all the insects logged in Tokyo (71 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.
