In 3 days ~10%
Cylindromyia interrupta is a species of fly in the family Tachinidae. This species is present in most of Europe, Russia and in North America ( Alaska to California, North Dakota, Colorado and New Jersey). These tachinid flies live in hedge rows and dry meadows.
Cylindromyia interrupta can reach a length of 6–8 millimetres (0.24–0.31 in) and a wingspan of 12 millimetres (0.47 in). Body is slender. Thorax is black, while the abdomen is reddish with two silver rings, a wide longitudinal black marking and black apical tergites. Hind tibiae have 1 or 2 posteroventral bristles. Apical scutellars are absent. The abdomen has median discal bristles on tergites 1, 2, 3 and 4. The bright white calypters stand out.
Adults can be found from May to August. They mainly feed on nectar and pollen of Apiaceae (especially Leucanthemum vulgare). This tachinid fly parasitizes moths and true bugs (Hemiptera). The larvae develop inside the living host. Wikipedia →

Rare
Under 5% of wildlife watchers report a Cylindromyia interrupta sighting in Toronto on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1544th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cylindromyia interrupta in Toronto on a given day, so our monthly data shows no clear season.
Only Toronto, in our data
Toronto is the only city on Wallace's Line with enough records to rate Cylindromyia interrupta sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cylindromyia interrupta is recorded against all the insects logged in Toronto (5 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.
