Flower Hill Farm BUTTERFLIES OF 2011 ~ Mourning Cloak and Red Admiral



Mourning Cloak Nymphalis antiopa is the first butterfly to appear in April here at Flower Hill Farm. It hibernates as an adult and will awaken sometimes earlier, when the temperatures rise and stay warmer for days . . .  as they often do in March.
They might crawl out from under a piece of bark or out of a small hollow opening in a tree.
I was surprised to learn that a Mourning Cloak butterfly can live up to ten months.
This male or female is perched on the ground and as you can see, there is hardly a sprout of green up yet. 



Mourning Cloak butterflies lay their eggs in such a way as might alarm those who care for their preferred host trees or shrubs. Their off-white ribbed eggs are fastened in large numbers of up to 250 placed often in rings around the main stems of host plants or trees. They prefer willows, poplars and birches but will also feed on maples, ash, roses and other trees and shrubs.
The caterpillars remain together chomping on the leaves and it may cause a most unaesthetic appearance for a small time, but the tree or shrub will not die from these native caterpillars that must not be confused with the invasive non-native gypsy moth caterpillars.


Red Admiral Vanessa atalanta is also a migratory species like its cousin the American Painted Lady. I rarely see one of these lovely creatures. This May portrait is the only capture I have made, and it, sadly, is not a very good one.
If the migrating period is a success and you have nettles growing about your land or gardens, you might just have a visit from a Red Admiral . . . once referred to as Red Admirable.
Here on our hillside, these butterflies will lay a single egg, finely crafted into an exquisite green dome, upon the leaves of a variety of New England nettles. The caterpillars fasten the outer edges of a leaf together with silk and feed within the protected enclosure.
It will also make its chrysalis using this method . . .  hidden within the last leaf it folds. When it emerges as a butterfly, its sustenance tastes vary greatly from tree sap to decaying fruits and excrement. As my photo reveals, these butterflies also indulge in sipping nectar from flowers.
This Red Admiral might be a male that has migrated up from the south and has yet to find his mate. I truly have no knowledge for identifying the male from the female. Males will find a good look-out perch to wait and eye an area for a female. After three generations here the fall butterflies will again fly south but there is not enough research to know of their successful migration flights to a warmer climate. We know so much about the Monarchs migration, so hopefully more research will result in understanding these beautiful butterflies too.
You might help by going to the link above and sharing your information. 


Winter is a time for watching the sun and noting the remarkable turning and tilting of our earth, as we notice the sunrise moving from south to north painting brilliant sky paintings as it goes.
The Winter Solstice . . . around the time of the photograph above . . . and the Summer Solstice . . . close to the time of the photograph below . . . mark the times when the sun has climbed to its lowest and highest positions in the sky. The shortest and the longest days of sunlight occur on the solstices. 


Sunrise over the northern part of Walnut and Carey hill nearly one month after the Summer Solstice.


Now, the sun is spilling a wash of light stretching longer each day, as it continues to move farther away from the Winter Solstice towards the Spring Equinox, where light will be equal to night and onto the longest day with Summer Solstice.
These images showcase a few minutes as the sun rises over Walnut hill a few days ago. It is a winter ritual to stand and watch this new beginning and celebrate the amazing brilliance of color splashed across the clouds and sky.






You can still see the edge of blue belonging to the Mount Holyoke range in the bottom right corner of the photo above.
 In December the sun was rising more to the right, directly over the Mount Holyoke Range, as seen in the photo further above . . .  just below the Red Admiral photograph.
Now in March, the sun is cresting more to the north and left . . . climbing over the southern part of Walnut Hill.


We are in that time of year that is akin to a bucket filled with uncertainty like piling a stack of wood in the dark and when placing the last few small logs the entire pile tumbles down. You might believe you could feel your way through anything . . . but March, with the fluctuating degrees of chill and heat, can drag you down at times . . .  casting off a sudden six inches of snow that soon turns to hard packed ice.
The waxing moon pulls the mercury in the thermometers down into the single digits.
This years rising and falling of temperatures has been kind to our Maple Sugar Industry here in Western Massachusetts. It has been an early and lasting season so far, according to my friend and neighbor Roger (seen above in a 2010 photo - today we have much more snow.)
The sweet sap is running and before long spring will have her say and kindly bid farewell to winter . . . until another day.
Old man winter does so like to tease and may step back into the waking landscape with its frosty touch.
Hopefully Mourning Cloak butterflies will not be caught without their antifreeze!

Flower Hill Farm BUTTERFLIES OF 2011 ~ Favorite Viceroy



The Viceroy Limenitis archippus, is a bright orange butterfly with black veins, cleverly mimicking the bad tasting and tummy aching (for the birds) milkweed butterflies. It is classified as a Mullerian mimic of the Monarch butterfly.


Therefore upon first sighting the Viceroy, an observer may believe it to be a Monarch butterfly. There are many differences, however . . .  such as size and hue intensity . . .  but the easiest way to identify the Viceroy, is to note the thick black vein drawn horizontally through the hind wings. The monarch, as illustrated above, does not have this trait. Also, notice the drops of white. . . the color of milkweed sap . . .  are quite different in numbers and shapes.


The Viceroy may not be very tasty either but that does not keep the birds from trying to find out the hard way.


When spotting these beautiful butterflies further out in the gardens and fields, it is harder to determine the differences. One sure way to know a monarch from a viceroy . . . even faraway . . .  is in the unique and graceful soaring flight of the monarch.

Viceroy butterflies may have up to three broods during May through September. Females lay beautifully intricate pale green eggs . . . that mimic plant galls . . . on the leaves of willows, poplars and even apple and cherry trees. The third instar caterpillar of the last brood will fastidiously fashion a leaf, of its preferred host plant, into a safely fastened silk-lined shelter and wait out the fall, winter and early spring months here in the northeast. Mother nature has protected these little critters by adorning them in the most unappealing garments . . . resembling bird poop. Come spring, when sap begins to stir and rise up through veins of crusty trees . . .  reaching for extremities . . . tiny leaves begin unfurling, awaking sleeping caterpillars, who stretch and begin anew on their journey towards becoming rather dull, dark-brown and white chrysalises. The first boldly painted butterflies may emerge before many plants are flowering and find nourishment where they can . . .  in pools of water, decaying flesh, excrement and even by shrewdly sipping aphid honeydew. 


The sun sails a bit further north each longer winter day.



Robins fill the crabapples and reap the benefits of dried fruit.


 Marching towards spring is always unpredictable here in the northeast. Soft snow began falling on the hard frozen ground Wednesday afternoon continuing throughout Thursday . . .  the first day of March.



 The soft bluish landscapes above were taken just at dusk on Thursday. 
It is still very much winter here and all the overwintering caterpillars and chrysalises continue to dream while the farmers and gardeners long for spring. 
Luckily we have thousands of butterfly photos to edit and other gardens to visit. 
Friday is for flying away to Sweden to visit Katarina's Roses and Stuff.
Clicking into Katarina's and other wondrous gardens does help soften the hard cold fact of winter's continued chill.

Flower Hill Farm BUTTERFLIES OF 2011 ~ Favorite White Admiral and Red-spotted Purple


White Admiral (left) and Red-spotted Purple on Beauty bush 2009

When I began this series, I had thought to just include photos for 2011, but with some butterflies, and especially these, I am including some from the past three years. 
The link between the White Admiral Limenitis arthemis arthemis and the Red-spotted Purple Limenitis arthemis astyanax is a fascinating one.  If I understand it correctly, here in Massachusetts, the more southernly Red-spotted Purple and northern White Admiral forget their differences and blend together, mixing genes and some traits.  
Many now refer to the two species as one with the name Red-spotted Admiral.

Red-spotted Purple on Spirea June 18, 2011

Often I capture these butterflies on the same day a few hours apart or a few days apart. 
I cannot imagine any bird that would be fooled, but the Red-spotted Purple is a mimic for the toxic Pipevine Swallowtail
The Red-spotted Purple caterpillars prefer the black cherry but will also use crabapple and poplar as host plants and both are abundant here at Flower Hill Farm. They have been sighted on other plants as well. The links in red on my posts will take you to more information. The White Admiral does not enjoy Black Cherry it seems . . .  but prefers poplar or yellow and sweet birch. They also may dine on shadbushes, hawthorns and a few other plants and trees. 
As adult butterflies these beauties will choose to sip from some rather repugnant sources. Clearly they also enjoy the power of flowers. We may see both butterflies flying around from May to early October with the second brood overwintering in the third instar state. 

****************

I would like to share all of the nine butterflies I have featured in this series so far. 
The parade will continue on . . .  but for now . . .  I think you will agree with me that these gorgeous creatures look fabulous together in their varied vibrant frocks presented in garden mosaics.  
It gives me much joy to know that my gardens attract all these delightful pollinators. 
I have much work to do incorporating more native host plants and being more careful in how I manage the cutting of the fields, so as to protect the overwintering larva and chrysalises. 

Monarch, Eastern Black Swallowtail, Tiger Swallowtail, Common Buckeye, American 'Painted' Lady, Great Spangled Fritillary, Pearl Crescent, White Admiral, Red-spotted Purple


Can you match the open winged butterfly to its closed counterpart? 
I think these would make great puzzles.


Today is another sunny day . . . this winter the sun has been generous. Our resident bluebird is not alone anymore . . . I saw and heard two pairs this morning. They are becoming more animated with each day. Now (or earlier!) is the time to have those nest boxes in place. I have some new ones that must be put out this week. 
I do not recall ever seeing snowdrops this early . . .  there are a few showing a bit of their precious pendent white bells . . .  along the south facing trunk of a giant rock maple.

Flower Hill Farm BUTTERFLIES OF 2011 ~ Favorite Crescents



Now for some more of the lovely Brushfooted Butterflies of the Nymphalidae family.  
The wing patterns of the Pearl Crescent Phyciodes tharos, vary significantly as you will see in the three featured here. This butterfly was from a late May 2011 brood and is feasting on what I believe to be a Robin's Plantain Erigeron pulchellus

It is hard to believe that the third instar caterpillars of the last broods from September are wintering over out in the fields and gardens somewhere near their host native aster plants. I hope they are safe from the many juncos, goldfinches and robins who are constantly combing the snowless areas of ground. Though since the female butterfly deposits up to 700 eggs in groupings of 20 -300 on aster leaves, there may well be an abundance of surviving dormant caterpillars to spare a few tasty bites for the birds. Birds must survive the winter somehow too.

Male Pearl Crescent ~ Note Flat Tip of Abdomen
Another Late May Pearl Crescent Minus One Antenna

Another late May male, I am guessing,  but the outlines on all the wings are so much darker.  It might just be that I took this photo in a less sunny spot.  


These butterflies will nectar on most any flower. Above is a female enjoying marjoram flowers. Bright mid July sun washes out the more vivid colors of this  Pearl Crescent .


Female Pearl Crescent ~ Note Pointed Tip of Abdomen 

This female Pearl Crescent was captured feeding on a Rudbeckia in August of 2011. 


I find these butterflies even more difficult to identify than the varied Fritillaries. Sometimes just seeing the negative space can help us see forms. Each of these three different Pearl Crescents is on a different flower and I have them placed so as to show the varying patterns on the wings. By draining the color away in the top photos we can more easily see the patterns.

It is easiest to identify the Pearl Crescent by seeing her underwings. Note the pearly white crescent on the butterfly below. 

Flower Hill Farm 2010 ~ Note ~ Pearly Crescent on Underwing

In 2010 the middle garden/meadow was filled with hundreds of these tiny 1 - 1 1/2 inch wing span Pearl Crescents. It was magical walking amongst the multitude of sunlit wings flitting about the large stand of gooseneck.

Pearl Crescent 2009 in the spring garden

I found this image from the gardens of 2009. The variety of the wing patterns is so confusing but beautiful. I cannot believe anyone could call this small butterfly dull. 


We are still living out the mild winter of 2012 and though there are no beautiful butterflies flying about, there are plenty of birds that gather each morning atop Michael's Black Cherry to await the rising sun. The colors of the goldfinches are beginning to turn yellow again. 
One solitary bluebird seems to hangout with nearly fifty finches. I hope they help keep him warm at night.



The golden sun is climbing farther to the north each day along Walnut Hill. March is nearly here and spring will not be far for this corner of New England. 

It is time to visit Gail for Wildflower Wednesday! 
Katarina is offering the word Color this week.
