Rare
Under 5% of wildlife watchers report a Dark Longhorn sighting in Paris on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 827th most-seen of the 916 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.
April
In that month about 10% of wildlife watchers report a Dark Longhorn in Paris on a given day, against under 5% in May to March, the lowest months.
Only Paris, in our data
Paris is the only city on Wallace's Line with enough records to rate Dark Longhorn sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Apidae
The closest relatives of the Dark Longhorn that you can see in Paris (family Apidae, Honey Bees, Bumble Bees, and Allies) are Common Carder Bumble Bee (about 30%), Hairy-Footed Flower Bee (about 10%) and Buff-Tailed Bumble Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dark Longhorn is recorded against all the insects logged in Paris (7 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.
