Tasmania is located south of the mainland of Australia, separated from the state of Victoria by the 240 km wide Bass Strait. Although Tasmania shares most of its fauna with the southern parts of Australia or Australia as a whole, Tasmania's isolation along with its wetter, cooler and cloudier weather caused the evolution of several endemic Tasmanian species and subspecies, butterflies included. There are thirty-nine species of butterflies found in Tasmania. They are grouped primarily as: skippers, blues, browns, swallowtails and the introduced whites.
