With luck
About 10% of wildlife watchers report a Cerastis faceta sighting in Porto on a given day, based on 61 verified sightings from GBIF citizen-science data. It is the 113th 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.

GBIF citizen-science records
It is estimated from how often the Cerastis faceta is recorded against all the insects logged in Porto (61 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.
