Rare
Under 5% of wildlife watchers report a Common Gluphisia Moth sighting in Toronto on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 732nd 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 Common Gluphisia Moth in Toronto on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Common Gluphisia Moth sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 10 cities where we can rate Common Gluphisia Moth sightings, Toronto ranks 6th at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%), Montreal (Canada, under 5%) and Edmonton (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Gluphisia Moth is recorded against all the insects logged in Toronto (19 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.
