Rare
Under 5% of wildlife watchers report an Iberian Field Grasshopper sighting in Pyrénées National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 869th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report an Iberian Field Grasshopper in Pyrénées National Park on a given day, against under 5% in November to August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Iberian Field Grasshopper sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Iberian Field Grasshopper sightings, Pyrénées National Park ranks 3rd at under 5%. The best odds are in Sierra Nevada National Park (Spain, about 10%) and Sierra de Guadarrama National Park (Spain, about 10%).

GBIF citizen-science records
It is estimated from how often the Iberian Field Grasshopper is recorded against all the insects logged in Pyrénées National Park (8 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.
