Phaneroptera falcata
In 3 days ~20% in a week ~40%
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 Pyrénées National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 363rd most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Sickle-Bearing Bush-Cricket in Pyrénées National Park on a given day, against under 5% in October and December–June, 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.
Among the best
Of the 2 parks where we can rate Sickle-Bearing Bush-Cricket sightings, Pyrénées National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Bavarian Forest National Park (Germany, 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 Pyrénées National Park (27 verified sightings from 2019 to 2026), 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.
