Rare
Under 5% of wildlife watchers report a Woodland Dor Beetle sighting in Paris on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 333rd 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 30%, if each day is a fresh chance.
August to November
In those months about 10% of wildlife watchers report a Woodland Dor Beetle in Paris on a given day, against under 5% in December to July, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Woodland Dor Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
13th of 17
Of the 17 cities where we can rate Woodland Dor Beetle sightings, Paris ranks 13th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Helsinki (Finland, about 10%) and Warsaw (Poland, about 10%).
Same order: Coleoptera
The closest relatives of the Woodland Dor Beetle that you can see in Paris (order Coleoptera, Beetles) are Asian Lady Beetle (about 40%), Seven-Spotted Lady Beetle (about 30%) and European Rose Chafer (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Woodland Dor Beetle is recorded against all the insects logged in Paris (22 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.
