Rare
Under 5% of wildlife watchers report a Carabus purpurascens sighting in Brussels on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 295th most-seen of the 337 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–April and June
In those months about 10% of wildlife watchers report a Carabus purpurascens in Brussels on a given day, against under 5% in May and July–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Carabus purpurascens sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Brussels, in our data
Brussels is the only city on Wallace's Line with enough records to rate Carabus purpurascens 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 purpurascens is recorded against all the insects logged in Brussels (5 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.
