Rare
Under 5% of wildlife watchers report a Coastal Pearl sighting in Lisbon on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 266th 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 20%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Coastal Pearl in Lisbon on a given day, against under 5% in July to May, the lowest months. That is one of Lisbon's driest months, with about 15 mm of rain against 95 mm in November.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Coastal Pearl sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Lisbon, in our data
Lisbon is the only city on Wallace's Line with enough records to rate Coastal Pearl sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Coastal Pearl that you can see in Lisbon (family Crambidae, Crambid Snout Moths) are Jasmine Moth (about 10%), Rush Veneer (about 10%) and Narrow-Winged Grey (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Coastal Pearl is recorded against all the insects logged in Lisbon (10 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.
