In 3 days ~10% in a week ~20%
Perispasta is a genus of moths of the family Crambidae. It contains only one species, Perispasta caeculalis, or Titian Peale's pyralid moth, which is found in North America, where it has been recorded from Quebec west to British Columbia, south to Florida, Texas and Colorado. The habitat consists of fields and meadows. Both the genus and species were first described by Philipp Christoph Zeller in 1875.
The wingspan is 16–18 mm. The forewings are dark brown with a white discal bar. The hindwings are white. Adults have been recorded on wing from January to November, depending on the location. Wikipedia →

Rare
Under 5% of wildlife watchers report a Titian Peale's Moth sighting in Montreal on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 634th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Titian Peale's Moth in Montreal 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 Titian Peale's Moth sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 cities where we can rate Titian Peale's Moth sightings, Montreal ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Dallas (United States, under 5%) and Toronto (Canada, under 5%).
Same family: Crambidae
The closest relatives of the Titian Peale's Moth that you can see in Montreal (family Crambidae, Crambid Snout Moths) are Box Tree Moth (about 10%), Canadian Petrophila (about 10%) and Elegant Grass-Veneer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Titian Peale's Moth 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.
