This image, from page 147 of Butterfly by Thomas Marent, shows the common swallowtail we called the Tiger Swallowtail where I grew up. It occurs throughout the Northern hemisphere. It was not a very common sight fifty years ago, but is now one of the more commonly seen butterflies, one of the survivors of the habitat and toxin assault that has decimated butterfly populations.
Butterfly is a coffee-table book, and I couldn't resist it, in spite of its size (my place is cluttered enough already). I scanned a few images from the book that show how the author presents all life stages of butterflies and moths. I am not sure how your browser will group the next three images, so I present them in a clump. First the egg, not of the swallowtail but of a ringlet (p 78); then the head of a swallowtail larva (p 87); finally a swallowtail pupa, or chrysalis (p 135). A section of the book covers metamorphosis, including some larvae that change appearance with each molt.
