With luck
About 10% of wildlife watchers report a Southern Gatekeeper sighting in Lisbon on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 441 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 to August
In those months about 10% of wildlife watchers report a Southern Gatekeeper in Lisbon on a given day, against under 5% in September to April, the lowest months. Those are among Lisbon's driest months, with about 15 mm of rain a month against 95 mm in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Southern Gatekeeper 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 4 cities where we can rate Southern Gatekeeper sightings, Lisbon ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Barcelona (Spain, about 10%) and Madrid (Spain, about 10%).
GBIF citizen-science records
It is estimated from how often the Southern Gatekeeper is recorded against all the insects logged in Lisbon (32 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.
