Karner Butterfly

( Lyceaides melissa samuelis)

Karner Butterflies:

First determined and called by ist as well as lepidopterist Vladimir Nabokov. The name stems from Karner, (situated half-way in between Albany as well as Schenectady,, in the Pine ), where it was initial found.

Habitat currently ranges from Hampshire to Minnesota, their populaces are restricted to specialized environments where wild blue lupine plants (Lupinus perennis), are located.

Grown-up butterflies have a wing period of just one inch and usually live just a few days to a few weeks.

Male and also women butterflies can be differentiated by the tinting on the top side of their wings.

The top side of the male’s wings is a violet blue with black margins and white fringed sides.

The violet blue color is just seen on the main part of the top side of the women wings, with the rest a dark gray-brown.

enhancement, limited orange crescents are commonly present on the back wings of the woman.

The underside of the wings of both males as well as ladies is gray with black areas.

Near the edges of the bottoms of both wings are orange crescents as well as metal places.

The orange crescents on the bottom of the forewings may be very difficult to see on butterflies from the eastern component of the array, particularly males.

Nectar Plant kingdoms:

Grownup Karner blues prey on the nectar of many plants, a few of their favorites are Butterfly weed (Asclepious tubersoa) Leafed spurge (Euphorbia podperae), Blazing celebrity (Liatris cylindracea), strawberry (Fragaria virginiana), and also Jersey tea (Ceanothus americanus).

As they feed upon nectar, some plant pollen stays with the grown-up butterfly and also is unintentionally moved from flower to flower. This transfer of pollen is most likely to cause some pollination.

Recreation and Host Plants:

Females just lay their eggs on or near lupine plants.

After hatching out, the young caterpillars feed on the lupine. After a few weeks of feeding, the caterpillars develop a chrysalis.

Karner blue caterpillars just eat wild blue lupine leaves, leaving « laquo windowpanes raquo or a leaf laquo skeleton raquo . blue lupines are discovered in the sandy soils of yearn barrens, oak savannas as well as lake shore dune environments.

( These habitats need fire or various other disturbance to preserve the warm open spots where wild blue lupine is found, as well as they usually support other rare varieties as well as common types like Butterfly weed ans Coreopsis.)

Like lots of members of the Lycaenid butterfly family (the blues as well as coppers), this little blue butterfly caterpillars are « laquo often tended raquo by ants.

The caterpillars secrete little amounts of a liquid from a gland on the top rear of the caterpillar. various other types that have actually been studied these secretions consist of sugars as well as in some cases amino acids, that offer food to the ants.

The caterpillar obtains something in return from the ants: security from some predators and parasites. Caterpillars with ants are most likely to make it through than those that do not have ant assistants.

Grownups arise in concerning 10 days. Two generations of Karner blues are generated each year.

Eggs of the second brood overwinter, to hatch the following.


These little butterflies were government noted as endangered in 1992, because of remarkable declines in populaces because of environment loss as well as alterations, such as fire suppression.

Generally, during the last couple of years the population range-wide appears secure. However, declines over the previous numerous years have been kept in mind in, where Karner blue butterfly sites and population levels are low compared to the remainder of their array.

Wisconsin and Michigan sustain more as well as bigger populations of the varieties than the staying states in their variety (NH, NY, IN, OH as well as MN).

Karner blue butterfly reintroductions are underway in Hampshire, Ohio, and Indiana, with the goal of restoring practical populaces in those states. Research on environment administration, dispersal, ant tending, as well as female egg-laying choices are aiding with the administration of the butterfly.

Protection of the Karner blue butterfly, wild blue lupine, and also the habitat where they live is likely to help in the survival of lots of other plants and pollinators that additionally thrive in these rare environments.
