Rare
Under 5% of wildlife watchers report an Apriona rugicollis sighting in Beijing on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 349th 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 an Apriona rugicollis 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 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Apriona rugicollis sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
10th of 10
Of the 10 cities where we can rate Apriona rugicollis sightings, Beijing ranks 10th at under 5%. The best odds are in Hangzhou (China, about 10%), Taichung (Taiwan, about 10%) and Taipei (Taiwan, about 10%).
Same family: Cerambycidae
The closest relatives of the Apriona rugicollis that you can see in Beijing (family Cerambycidae, Longhorn Beetles) are Thin-Winged Longicorn Beetle (about 10%), Red Necked Longhorn Beetle (about 10%) and Asian Longhorned Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Apriona rugicollis is recorded against all the insects logged in Beijing (6 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.
