Looking Up!

The Canadain Tiger Swallowtail is "a big, bright elegant butterfly, with soaring wingbeats and fraceful lines. And why do swallowtails have "tails" on their hindwings? So that the birds will grasp these conspicious "appendages" and fly away with a beak full of membrane, rather than the butterfly itself. ther are five species of swallowtails in Alberta."
~ John Acorn & Ian Sheldon Bugs of Alberta
