Rare
Under 5% of wildlife watchers report a Harpalus chalcentus sighting in Beijing on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 159th 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.
March–April and October–November
In those months about 10% of wildlife watchers report a Harpalus chalcentus in Beijing on a given day, against under 5% in May–September and December–February, the lowest months. Those are among Beijing's driest months, with about 20 mm of rain a month against 150 mm in July.
2nd of 3
Of the 3 cities where we can rate Harpalus chalcentus sightings, Beijing ranks 2nd at under 5%. The best odds are in Hefei (China, about 20%).
GBIF citizen-science records
It is estimated from how often the Harpalus chalcentus is recorded against all the insects logged in Beijing (16 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.
