PORTLAND, OR– The Xerces Society for Invertebrate Conservation, Oregon Wild, and noted butterfly expert Dr. David V. McCorkle filed a petition today seeking Endangered Species Act protection for Leona’s little blue butterfly (Philotiella leona).
A single population of Leona’s little blue butterfly found in the Antelope Desert in Klamath County, Oregon is the only population of the species known to exist in the world. This highly endemic species occupies a specialized niche within a volcanic pumice and ash ecosystem on private timberland and a small part of the Winema National Forest.
“With only 2,000 individuals of this species remaining in such a small area, a single event – such as a wildfire or a pesticide used indiscriminately – could lead Leona’s little blue to extinction,” said Sarina Jepsen, Endangered Species Program Director of The Xerces Society. “The Endangered Species Act can help protect this butterfly and its habitat."
Leona’s little blue is threatened by conifer encroachment, catastrophic and controlled fire, cinder pit mining, insecticide and herbicide use, logging related activities, and livestock grazing. Potential changes in land management that may occur with a pending change in the ownership of the majority of this butterfly’s habitat could further imperil this blue butterfly. Without protection under the Endangered Species Act, this species is likely to go extinct.
“Leona’s little blue butterfly can be considered an indicator of the health the Antelope desert,” said Ani Kame’enui of Oregon Wild. “This butterfly may be small, but by protecting its critical habitat under the Endangered Species Act, we will safeguard an essential piece of wild Oregon.”
Recognizing the dire situation the butterfly faces, NatureServe lists this species as Critically Imperiled. Today’s petition requests that the U.S. Fish and Wildlife Service list this highly threatened species as endangered under the U.S. Endangered Species Act.
"Leona’s little blue butterfly urgently needs the legal protections of the Endangered Species Act," stated Scott Hoffman Black, Executive Director of The Xerces Society. "Mounting threats to the single population of this butterfly include tree encroachment on its open habitat, cinder pit mining, wildfire, timbering activities, and pesticide use.”
