Old World Swallowtail (Papilio Machaon)

A familiar sight throughout the world, the Old World Swallowtail butterfly comes in a slight variation in Israel. 

Zablow, a native of Brooklyn, describes it as "starkly beautiful ... almost unapproachable, and a challenge to locate." 

But once you catch a glimpse, it's all worth it. The striking pattern atop a pale yellow background, with a splash of blue – this butterfly stands out.
