Short-tailed Swallowtail (Papilio brevicauda)
Gaspesie National Park, QC 2013/08/01
Member of Family: Papilionidae
French common name: Papillon queue-courte
This species is endemic to Eastern Canada. In the Maritimes, it is found along the North and North-eastern coast of New Brunswick, and Northern Cape Breton. The photo shown above is the only one I have so far. Unfortunately, this individual was in poor condition, and the tails are missing.
