Rare
Under 5% of wildlife watchers report an Iberian Field Grasshopper sighting in Porto on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 290th most-seen of the 498 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.
May–June and August–September
In those months about 10% of wildlife watchers report an Iberian Field Grasshopper in Porto on a given day, against under 5% in July and October–April, the lowest months. Those are among Porto's driest months, with about 40 mm of rain a month against 140 mm in January.
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 cities where we can rate Iberian Field Grasshopper sightings, Porto ranks 3rd at under 5%. The best odds are in Lisbon (Portugal, about 10%) and Madrid (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 Porto (14 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.
