Rare
Under 5% of wildlife watchers report a Poplar Borer sighting in Edmonton on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 230th most-seen of the 390 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.
July
In that month about 10% of wildlife watchers report a Poplar Borer in Edmonton on a given day, against under 5% in August to June, the lowest months. That is one of Edmonton's wettest months, with about 95 mm of rain against 20 mm in February.
Only Edmonton, in our data
Edmonton is the only city on Wallace's Line with enough records to rate Poplar Borer sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Poplar Borer is recorded against all the insects logged in Edmonton (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.
