With luck
About 10% of wildlife watchers report an Iberian Field Grasshopper sighting in Lisbon on a given day, based on 51 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 441 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.
May and September–November
In those months about 10% of wildlife watchers report an Iberian Field Grasshopper in Lisbon on a given day, against under 5% in June–August and December–April, 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 cities where we can rate Iberian Field Grasshopper sightings, Lisbon has the highest daily chance: about 10%. Next come Madrid (Spain, about 10%) and Porto (Portugal, under 5%).
GBIF citizen-science records
It is estimated from how often the Iberian Field Grasshopper is recorded against all the insects logged in Lisbon (51 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.
