Some might say it takes a rare breed to survive the Alaska wilderness. The discovery of a possible new species of hybrid butterfly from the state's interior is proving that theory correct.

Belonging to a group known as the Arctics, the Tanana Arctic,Oeneis tanana, is the first new butterfly species described from the Last Frontier in 28 years and may be its only endemic butterfly.

University of Florida lepidopterist Andrew Warren suggests the butterfly could be the result of a rare and unlikely hybridization between two related species, both specially adapted for the harsh arctic climate, perhaps before the last ice age. Details of the finding are available online in the Journal of Research on the Lepidoptera.

Digging deeper into the Tanana Arctic's origins may reveal secrets about the geological history of arctic North America and the evolution of hybrid species, said Warren, who led the new study.
