Canadian Tiger Swallowtail: Harbinger of Spring

The Canadian Tiger Swallowtail (Papilio canadensis) is one of Canada's most recognizable butterflies. With its broad wingspan of up to ten centimetres and the distinctive yellow and black tiger stripe pattern on its wings and body, the Canadian Tiger Swallowtail is a striking feature of springtime in Canada.

The Swallowtail's showiest attributes - its wings - are also itsmost fascinating. The name of the order for all butterflies, Lepidoptera, means scale winged and refers to the unique structure ofbutterfly wings, which are composed of microscopic scales layered on a thin, transparent membrane called chitin that stretches over structures that are much like veins. This wing construction, which is being studied by scientists for applications in photonics and solar heating, helps butterflies to collect solar heat as they bask in the sun. The black colouring common on the wings of many butterflies, including the Canadian Tiger Swallowtail, is also important in this process. The unique internal structure of the wing scales is responsible for the shimmering colour of many butterfly wings.
