Rare
Under 5% of wildlife watchers report a Gold-Striped Grass-Veneer sighting in Toronto on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1005th 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 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 Gold-Striped Grass-Veneer in Toronto on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Gold-Striped 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 6 cities where we can rate Gold-Striped Grass-Veneer sightings, Toronto ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Baltimore (United States, under 5%), Washington (United States, under 5%) and Philadelphia (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Gold-Striped Grass-Veneer is recorded against all the insects logged in Toronto (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.
