Necedah NWR: No. 2 of 8

“We’ve got the world’s largest population of the Karner blue butterfly, which is a federally endangered species,” says Leann Wilkins, acting manager of the Necedah NWR. “In 2015, we had just under 12,400 Karner blue butterflies. They’re localized here, and don’t migrate, because their lifecycle depends on the wild lupine.”

Necedah NWR: No. 3 of 8

Adult Karner blue butterflies "emerge just as the lupine bloom in May," says Wilkins. "They’re alive just long enough to mate and lay eggs of another generation that emerges in late July and August, and that generation lays the eggs that will overwinter and hatch the following spring.”
