Rare
Under 5% of wildlife watchers report a Cerastis faceta sighting in Lisbon on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 361st 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.
December
In that month about 10% of wildlife watchers report a Cerastis faceta in Lisbon on a given day, against under 5% in January to November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Cerastis faceta is recorded against all the insects logged in Lisbon (6 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.
