Rare
Under 5% of wildlife watchers report a Toothed Somberwing sighting in Toronto on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 867th 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 Toothed Somberwing in Toronto on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Toothed Somberwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Toothed Somberwing sightings, Toronto ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Edmonton (Canada, under 5%) and Montreal (Canada, under 5%).
Same family: Erebidae
The closest relatives of the Toothed Somberwing that you can see in Toronto (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Spongy Moth (about 20%), Hickory Tussock Moth (about 10%) and Isabella Tiger Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Toothed Somberwing is recorded against all the insects logged in Toronto (14 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.
