Rare
Under 5% of wildlife watchers report a Schwarzerium quadricollis sighting in Tokyo on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 929th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Schwarzerium quadricollis in Tokyo on a given day, so our monthly data shows no clear season.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Schwarzerium quadricollis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cerambycidae
The closest relatives of the Schwarzerium quadricollis that you can see in Tokyo (family Cerambycidae, Longhorn Beetles) are Citrus Longhorn Beetle (about 10%), Paraglenea fortunei (about 10%) and Aeolesthes chrysothrix (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Schwarzerium quadricollis is recorded against all the insects logged in Tokyo (5 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.
