What are Karner Blue Butterflies?<\/h2>\n\n\n\n

Karner blues are small butterflies found in scattered regions<\/a> of the Great Lakes and New England states. They used to have a much larger range, but their numbers have fallen drastically due to loss of habitat and climate change.<\/p>\n\n\n\n

They have been federally listed as an endangered species<\/a> since 1992. For this reason, efforts have been made to preserve their current habitats and restore their numbers<\/a>.<\/p>\n\n\n\n

Karner blues live in pine barrens and oak savannas, which are relatively rare ecosystems. Their survival depends on the wild blue lupine plant, which often dies off due to succession in these ecosystems.<\/strong><\/p>\n\n\n\n

The Karner blue life cycle begins in April to May each year, when larvae hatch from overwintering eggs. These larvae reach adulthood by early June.<\/p>\n\n\n\n

These summer butterflies mate and lay eggs<\/a> before dying within a few days to a few weeks. Their eggs hatch within a week, and this second batch of butterflies reach adulthood by mid-August.<\/p>\n\n\n\n

These butterflies then mate and lay eggs that will remain dormant until the following spring, at which point, the cycle starts over.<\/p>\n\n\n\n
