With luck
About 10% of wildlife watchers report an Iberian Scarce Swallowtail sighting in Porto on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 71st most-seen of the 498 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July to September
In those months about 20% of wildlife watchers report an Iberian Scarce Swallowtail in Porto on a given day, against under 5% in December to March, the lowest months. Those are among Porto's driest months, with about 30 mm of rain a month against 140 mm in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Iberian Scarce Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5

GBIF citizen-science records
It is estimated from how often the Iberian Scarce Swallowtail is recorded against all the insects logged in Porto (70 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.
