With luck
About 10% of wildlife watchers report an Iberian Field Grasshopper sighting in Sierra Nevada National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 282nd most-seen of the 479 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.
May and July
In those months about 20% of wildlife watchers report an Iberian Field Grasshopper in Sierra Nevada National Park on a given day, against under 5% in September to March, 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.
Yes
Of the 3 parks where we can rate Iberian Field Grasshopper sightings, Sierra Nevada National Park has the highest daily chance: about 10%. Next come Sierra de Guadarrama National Park (Spain, about 10%) and Pyrénées National Park (France, under 5%).

GBIF citizen-science records
It is estimated from how often the Iberian Field Grasshopper is recorded against all the insects logged in Sierra Nevada National Park (7 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.
