Rare
Under 5% of wildlife watchers report a Blood Vein sighting in Beijing on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 260th 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
In that month about 10% of wildlife watchers report a Blood Vein in Beijing on a given day, against under 5% in September to July, the lowest months. That is one of Beijing's wettest months, with about 110 mm of rain against almost none in January.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Blood Vein sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
24th of 25
Of the 25 cities where we can rate Blood Vein sightings, Beijing ranks 24th at under 5%. The best odds are in Kharkiv (Ukraine, about 40%), Kyiv (Ukraine, about 10%) and Turin (Italy, about 10%).
GBIF citizen-science records
It is estimated from how often the Blood Vein 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.
