» Life History
Karner blues are found in the northern range of wild lupine habitat. Wild lupine (Lupinus perennis) is an attractively flowered plant that occurs in pine barrens and oak savannas in Indiana, Michigan, Minnesota, New Hampshire, New York, and Wisconsin. The Karner blue's habitat is a patchwork of pine and scrub oak scattered among open grassy areas. Historically, a network of these openings among the trees was maintained by wildfire and at one time the butterfly was found in this habitat in a nearly continuous narrow band across 10 states and one province. Today it has been eliminated from at least five of these states.
Karner blue caterpillars feed only on the leaves of the wild lupine plant. Adults feed on the nectar of flowering plants. This severely restricts where they can survive.
The Karner blue butterfly usually has two generations, and thus two hatches, each year. In April, the first group of caterpillars hatch from eggs that were laid the previous year. The caterpillars feed only on wild lupine plant leaves. By about mid-May, the caterpillars pupate and adult butterflies emerge from their cocoon-like chrysalis by the end of May or in early June. These adults mate, laying their eggs in June on or near wild lupine plants. The eggs hatch in about one week and the caterpillars feed for about three weeks. They then pupate and the summer's second generation of adult butterflies appears in July. These adults mate and lay eggs that will not hatch until the following spring.
