Rare
Under 5% of wildlife watchers report an Iberian Glow-Worm sighting in Porto on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 422nd 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 20%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report an Iberian Glow-Worm in Porto on a given day, against under 5% in September to June, the lowest months. Those are among Porto's driest months, with about 20 mm of rain a month against 140 mm in January.
Only Porto, in our data
Porto is the only city on Wallace's Line with enough records to rate Iberian Glow-Worm sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Lampyridae
The closest relatives of the Iberian Glow-Worm that you can see in Porto (family Lampyridae, Fireflies) are Portuguese Firefly (about 10%) and Lesser Black Glow-Worm (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Iberian Glow-Worm is recorded against all the insects logged in Porto (7 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.
