Rare
Under 5% of wildlife watchers report a Toothed Somberwing sighting in Montreal on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 599th 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.
June
In that month about 10% of wildlife watchers report a Toothed Somberwing in Montreal on a given day, against under 5% in July to May, the lowest months.
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, Montreal ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Edmonton (Canada, under 5%).
Same family: Erebidae
The closest relatives of the Toothed Somberwing that you can see in Montreal (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Isabella Tiger Moth (about 20%), Spongy Moth (about 10%) and Hickory Tussock 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 Montreal (9 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.
