With luck
About 10% of wildlife watchers report a Portuguese Firefly sighting in Porto on a given day, based on 91 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 498 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May and June
In those months about 20% of wildlife watchers report a Portuguese Firefly in Porto on a given day, against under 5% in August to April, the lowest months. Those are among Porto's driest months, with about 45 mm of rain a month against 140 mm in January.
Yes
Of the 2 cities where we can rate Portuguese Firefly sightings, Porto has the highest daily chance: about 10%. Next come Lisbon (Portugal, under 5%).
GBIF citizen-science records
It is estimated from how often the Portuguese Firefly is recorded against all the insects logged in Porto (91 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.
