Rare
Under 5% of wildlife watchers report a Southern Gatekeeper sighting in Porto on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 320th 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.
June to August
In those months about 10% of wildlife watchers report a Southern Gatekeeper in Porto on a given day, against under 5% in September to May, the lowest months. Those are among Porto's driest months, with about 20 mm of rain a month against 140 mm in January.
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.
4th of 4
Of the 4 cities where we can rate Southern Gatekeeper sightings, Porto ranks 4th at under 5%. The best odds are in Barcelona (Spain, about 10%), Madrid (Spain, about 10%) and Lisbon (Portugal, about 10%).
GBIF citizen-science records
It is estimated from how often the Southern Gatekeeper is recorded against all the insects logged in Porto (13 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.
