Rare
Under 5% of wildlife watchers report a Double-Banded Grass-Veneer sighting in Toronto on a given day, based on 96 verified sightings from GBIF citizen-science data. It is the 256th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Double-Banded Grass-Veneer in Toronto on a given day, against under 5% in August to May, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Double-Banded Grass-Veneer sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 8 cities where we can rate Double-Banded Grass-Veneer sightings, Toronto ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Chicago (United States, under 5%) and Montreal (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Double-Banded Grass-Veneer is recorded against all the insects logged in Toronto (96 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.
