CONCORD, N.H. (AP) - The Karner blue butterfly, once considered extinct in New Hampshire, has made a comeback.
The state Fish and Game Department says the number of butterflies marked in the wild surpassed the previous high number observed in 2010, which was more than 2,600. This year's final count is still being worked on.
The department says good weather, coupled with help extending the butterfly's habitat in Concord, have made a difference. A company called Praxair Surface Technology created a 10- to 15-acre habitat to attract the brilliant blue butterflies, planting over 600 blue lupine and nectar plants.
The butterfly has been on the federal Endangered Species list since 1992. That year it also was named New Hampshire's state butterfly, which has been working to restore their unique, savannah-like habitat.
