Rare
Under 5% of wildlife watchers report an Alfalfa Curculio sighting in Edmonton on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 202nd 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.
May and June
In those months about 10% of wildlife watchers report an Alfalfa Curculio in Edmonton on a given day, against under 5% in July to April, the lowest months. Those are among Edmonton's wettest months, with about 75 mm of rain a month against 20 mm in February.
Only Edmonton, in our data
Edmonton is the only city on Wallace's Line with enough records to rate Alfalfa Curculio sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Alfalfa Curculio is recorded against all the insects logged in Edmonton (12 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.
