Rare
Under 5% of wildlife watchers report a Carabus strasseri sighting in Porto on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 320th 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 30%, if each day is a fresh chance.
March, August and November
In those months about 10% of wildlife watchers report a Carabus strasseri in Porto on a given day, against under 5% in April–July, September–October and December–February, the lowest months.
Only Porto, in our data
Porto is the only city on Wallace's Line with enough records to rate Carabus strasseri sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Carabus strasseri is recorded against all the insects logged in Porto (11 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.
