In 3 days ~10% in a week ~20%
Paracorsia is a monotypic genus of moth in the family Crambidae described by H. Marion in 1959. It contains only one species, Paracorsia repandalis, described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in most of Europe, except Ireland, Fennoscandia and the Baltic region. It has also been recorded from central Asia, including Iran and Kyrgyzstan and North America where it has been recorded in southern Ontario and northern Indiana.
The wingspan is 24–28 mm. Adults are on wing from April to October in two generations per year. The larvae feed on Verbascum species, including Verbascum lychnitis, Verbascum thapsus and Verbascum phlomoides. Pupation occurs in early spring after hibernating in a case. Wikipedia →

Under 5% of wildlife watchers report a Scarce Straw Pearl sighting in Toronto on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 704th 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 Scarce Straw Pearl in Toronto on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Scarce Straw Pearl is recorded against all the insects logged in Toronto (20 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.
