Canadian tiger swallowtail
Big yellow butterfly with black stripes and blue/orange spots near its swallow-like tail. Caterpillars resemble small green or brown snakes, complete with eye-spots.
Fluttering lazily about the air near deciduous forests, or (as caterpillars) motoring along the sidewalk, looking like a snake.
Occasionally confused with:
Old World or anise swallowtails, which are smaller and have black blotches instead of stripes on their wings.
The Canadian tiger swallowtail breeds just once a year, compared to the eastern tiger swallowtail, which breeds twice.
