Rare
Under 5% of wildlife watchers report a Grape Flower Plume Moth sighting in Montreal on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 556th most-seen of the 926 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.
June
In that month about 10% of wildlife watchers report a Grape Flower Plume Moth in Montreal on a given day, against under 5% in July to May, the lowest months.
Only Montreal, in our data
Montreal is the only city on Wallace's Line with enough records to rate Grape Flower Plume Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Grape Flower Plume Moth is recorded against all the insects logged in Montreal (10 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.
