MBC Field Trip to Karner Blue Butterfly Conservation Easement

Eleven people participated in the Massachusetts Butterfly Club walk just across the state line in Concord, New Hampshire searching for endangered Karner Blue butterflies.  We found them!  Lupine was in bloom along the highways and also in the conservation easement itself.  I loved the huge patches of lupine along the highways, but there's no place to stop to record it!


Karner Blue butterflies require wild lupine as a host plant (on which they lay their eggs and whose flowers the resulting caterpillars will eat for food) in a pine barrens habitat.  In 1992, the Karner Blue was voted to be the state butterfly of NH.  However, by 1999, there were none left in the state.  In 2000, the state of NY sent butterflies to help restore the population in NH, and since then, the population reached its highest count in 2010, when there were 2400 butterflies.  Last year they estimated there were about 1,500.  They hope to eventually maintain about 3000 butterflies for five straight years and expect to achieve this goal by 2017.  NH's program is so successful, they now export caterpillars to other states that are also working to restore lost populations.

Michael spotted the first Karner Blue very near where we posed for our group photo, so we were immediately off to a good start (because there are no guarantees of sightings)!

I thought this was the prettiest one, posing on the white flower and giving us glimpses of its beautiful blue interior wings.

After lunch, a smaller group of us took an extended trip to Ponemah Bog in Amherst, NH.  We only saw two additional butterflies here, but we all enjoyed the bog habitat and hope to return for Bog Coppers and Grass Pink orchids!

Sundew

My favorite part of my 2nd visit to Ponemah Bog was having Rosemary point out these Sundew plants.  They were so low to the ground and so small that I didn't notice they were sundew.  They are carnivorous but so beautiful!

The suns (circles) are surrounded with tentacles (rays) that end in sticky secretions (dew) that attract small insects.  The secretions perform multiple functions:  attracting prey, trapping prey, and then providing the enzymes to aid the digestion process.  Either exhaustion or suffocation results in death of the prey within about 15 minutes.  The enzymes dissolve the insect and the nutrient "soup" is then absorbed through the plant's surface.

Indian Skipper?

Downy Woodpecker
(Thanks, Josh, for pointing out the spots on the tail which clinch this ID.)
Hairy Woodpecker?

I can't be sure because it has something in its mouth which I can't distinguish from the bill.

  1. Dawn: I can see some black spots on the white tail feathers of the woodpecker. According to All About Birds, "Hairy Woodpeckers also have [...] in most populations, completely white outer tail feathers". So, I'd say this one is likely a Downy.
