Rare
Under 5% of wildlife watchers report a Dolichus halensis sighting in Beijing on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 201st most-seen of the 401 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.
June and August–September
In those months about 10% of wildlife watchers report a Dolichus halensis in Beijing on a given day, against under 5% in July and October–May, the lowest months. Those are among Beijing's wettest months, with about 85 mm of rain a month against almost none in January.
6th of 7
Of the 7 cities where we can rate Dolichus halensis sightings, Beijing ranks 6th at under 5%. The best odds are in Nagoya (Japan, about 10%), Seoul (South Korea, about 10%) and Osaka (Japan, about 10%).
Same family: Carabidae
The closest relatives of the Dolichus halensis that you can see in Beijing (family Carabidae, Ground Beetles) are Carabus brandti (about 10%), Harpalus pallidipennis (about 10%) and Diplocheila zeelandica (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dolichus halensis is recorded against all the insects logged in Beijing (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.
