Papilio canadensis, the Canadian tiger swallowtail, is a species of butterfly in the family Papilionidae. It was once classified as a subspecies of Papilio glaucus. The wingspan of this species is 67 to 80 mm. It is very similar to the eastern tiger swallowtail, but has a noticeably smaller wingspan. Unlike it, the forewing underside, yellow marginal band is continuous. The hindwing has many orange scales on both morphs. This species has also been known to hybridize with both the eastern and western tiger swallowtail, though extremely rarely.
The caterpillar is large and green with an enlarged head. It has four yellow dots and two false eyes with bluish centers. In profile, this caterpillar appears snake-like. The immature larvae are brown and white to mimic bird droppings, making them unappealing to predators.
This butterfly is found in most provinces and territories in Canada, as its name implies. Its range extends north of the Arctic Circle in the Yukon, and to Churchill in Manitoba, Little Shagamu River in Ontario, and to Schefferville in Quebec. It does not occur in southern British Columbia, being replaced there... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Canadian Tiger Swallowtail is recorded against all the insects logged in Glacier National Park (20 verified sightings from 2019 to 2026), 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.
