Rare
Under 5% of wildlife watchers report a Black-Beaked Green Weevil sighting in Vancouver on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 439th most-seen of the 482 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 Black-Beaked Green Weevil in Vancouver on a given day, so our monthly data shows no clear season.
Only Vancouver, in our data
Vancouver is the only city on Wallace's Line with enough records to rate Black-Beaked Green Weevil sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Curculionidae

GBIF citizen-science records
It is estimated from how often the Black-Beaked Green Weevil is recorded against all the insects logged in Vancouver (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.
