Rare
Under 5% of wildlife watchers report a Marsh Rhopalid sighting in Beijing on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 247th 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 20%, if each day is a fresh chance.
August and October
In those months about 10% of wildlife watchers report a Marsh Rhopalid in Beijing on a given day, against under 5% in September and November–July, the lowest months. Those are among Beijing's wettest months, with about 70 mm of rain a month against almost none in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Marsh Rhopalid sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Marsh Rhopalid sightings, Beijing ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Tokyo (Japan, under 5%) and Shanghai (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Marsh Rhopalid is recorded against all the insects logged in Beijing (9 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.
