In the Ottawa area, "true" or "pure" Canadian Tiger Swallowtails fly in the spring to early summer, and pure Eastern Tiger Swallowtails seem to be rare. However, a fresh population of tiger swallowtails appears every year in July, and they generally show hybrid morphological characters. Preliminary molecular studies indicate these are 60-80% P. canadensis and 20-40% P. glaucus. It's not fully understood how this is possible without P. glaucus in the area or very rare in the area. Additional studies are underway.
