Rare
Under 5% of wildlife watchers report a Mountain Ash Sawfly sighting in Vancouver on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 328th most-seen of the 482 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mountain Ash Sawfly 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 Mountain Ash Sawfly sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mountain Ash Sawfly is recorded against all the insects logged in Vancouver (9 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.
