With luck
About 10% of wildlife watchers report an Apriona rugicollis sighting in Shanghai on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 115th most-seen of the 215 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report an Apriona rugicollis in Shanghai on a given day, against under 5% in August and October–May, the lowest months. That is one of Shanghai's wettest months, with about 200 mm of rain against 55 mm in December.
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.
Among the best
Of the 10 cities where we can rate Apriona rugicollis sightings, Shanghai ranks 5th at about 10%, level with the leaders once rounded. 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 Shanghai (family Cerambycidae, Longhorn Beetles) are Citrus Longhorn Beetle (about 20%), Red Necked Longhorn Beetle (about 10%) and Thin-Winged Longicorn 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 Shanghai (12 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.
