Rare
Under 5% of wildlife watchers report a Small White Grass-Veneer sighting in Montreal on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 524th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Small White Grass-Veneer in Montreal on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Small White Grass-Veneer sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.

Of the 2 cities where we can rate Small White Grass-Veneer sightings, Montreal has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Small White Grass-Veneer is recorded against all the insects logged in Montreal (11 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.
