Rare
Under 5% of wildlife watchers report a Cyrtotrachelus thompsoni sighting in Shanghai on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 215 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.
May–June and August–October
In those months about 10% of wildlife watchers report a Cyrtotrachelus thompsoni in Shanghai on a given day, against under 5% in July and November–April, the lowest months.
Only Shanghai, in our data
Shanghai is the only city on Wallace's Line with enough records to rate Cyrtotrachelus thompsoni sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cyrtotrachelus thompsoni is recorded against all the insects logged in Shanghai (8 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.
