Have you heard of the Pine Tube Moth?  It was a new one to me!  Argyrotaenia pinatubana lives in pine trees and seems abundant in Eastern White Pine on the Refuge and well beyond too.   At this time of the year the Pine Tube Moth larva has bundled up to about 20 live pine needles with a silk it produces.  The bundle is fashioned into a tube; the binding silk on the inside of the tube.  The greenish-yellow larva (caterpillar) will eat some of the pine needles composing the tube from the tips down.  If too much is eaten it will build another tube.  Here is an illustration of a typical tube residence.

Below is is an actual Pine Tube Moth tube photographed on the Refuge.  Difficult to see unless one is looking for it.  Once you know what to look for you will find tubes are abundant.

As the weather starts to cool, the larva pupates in a chrysalis as is typical for moths and butterflies.  The moth will emerge in the spring.  Hopefully next spring there will be a moth picture to post.  Here is a photo of the chrysalis from an opened tube

According to several sources, the Pine Tube Moth is a minor pest only effecting aesthetics as the tube needles, especially the tips, will generally brown.  It is found from Canada to Florida and west into Minnesota and Wisconsin.  Jack Pine Tube Moth is a similar species found in our western states.  In some areas two generations may occur in one season.
 
I'll be looking for caterpillars in the early summer and again in the fall and moths also.  Yum!  (Yes.  Belted Kingfisher will eat insects too)
 
Hope to see you at my Refuge.

The Refuge has been quiet but still plenty of things to see and do there. 
 
Birding with John M: John Milhaven led a morning birding walk last Saturday.  Here is a partial list of sightings:
  • Eastern Bluebird
  • Blue Jay
  • Northern Cardinal
  • Gold-crown Kinglet
  • Common Grackle
  • Canada Goose
  • Mallard Duck
  • Great Blue Heron
  • Black-capped Chickadee
  • Tufted Titmouse
  • Down Woodpecker
  • Hairy Woodpecker
  • Belted Kingfisher (that's me!)
  • American Goldfinch
  • Dark-eyed Junco (slate-colored variant)
 
Representative pictures of each of these species photographed on the Refuge can be found at: http://farnwr.org/gallery1.html
 
Bunker Tour: Jan Wright led a bunker tour last Sunday.  It started in the Visitor Center with her presentation on the history of the ARNWR land especially from the time of the government taking of the land by eminent domain in 1942 during WWII.  Residents were only given ten days to pack up and move out and construction of the ammo depot and bunkers commenced almost immediately. The site was used to store munitions from navy vessels docking in Boston Harbor and surroundings.  The ammo was removed to enhance the safety of the harbor in case of accident or attack.  It was carried by rail  to be stored in the bunkers (officially know as "igloos").  The site (now ARNWR) which touches Maynard, Stow, Hudson and Sudbury was just out of the range of enemy battleship firepower of the time making it a safer prospect than storing anywhere near the city. 
 
Following the war it served for troop training, munitions testing and numerous projects associated with the Army's Natick Labs.  Camo gear, parachutes and other materials and equipment were tested here.  Our Refuge was established in 2000 but it was not opened to the public until structures were demolished and Superfund cleanup was completed.
 
Bunker #303 was opened.  It was dark and echoey and remarkably clean and fresh smelling.  I would have expected dank!  Click on the image below to see photos from the tour.

Flora & Flora Spotted Recently
 
Deer: spotted from a distance crossing Harry's Way near Kingfisher Trail.  These were very mature does, both unusually tall.  Legs too short for moose more reminiscent of elk but there are no Elk in this area.
 
Yellow-legged Meadowhawk Dragonflies are still about, particularly around Puffer Pond.

Remarkably these two are both males in mating position!  Thanks to both Betty and Jini Foster for help with identification.
 

Here's what Betty Wright has to say about Yellow-legged Meadowhawk Dragonflies:
  • They are the only Meadowhawks to fly in November; the latest to fly
  • They can feed at temperatures below 50 degrees
  • Eyes are reddish brown
  • Brown to yellow basal wing patches
  • Early legs are dull yellowish; the older legs are dull brown
  • Lack of black on legs and usually less black on the sides of the abdomen distinguish this species from other Meadowhawks
Here are some other comments from Betty:On KingfisherI saw a Kingfisher.  This surprised me, but according to David Sibley, while they will migrate, they will stay as far North as there is open water.  Mine could have been migrating or one that planned to winter here
 
On Earthworm: There is not a native earthworm in North America.  They are all invasives and come from Europe.  I am not sure whether we are better or worse for them

On Wintergreen: When I was much younger, the advice was to chew on Wintergreen leaves.  Now, people into herbal medicines like Arthur Haines say never chew the leaves


Betty will be a frequent contributor to this blog :-).  Welcome aboard Betty and thanks!

As the weather continues to cool the waterways within the Refuge will be resting place for migrating and returning waterfowl.  Keep an eye open for Mergansers, Buffleheads, Teal, Ring-necked Ducks and others.  Come on down and keep watch.   Though the Refuge is seemingly quiet there is a lot of work going on.  Beavers and muskrats are preparing and repairing their lodges and stockpiling materials for the long winter. Watch for their activity near sunrise and sunset.  Also look for new beaver work (gnawed and felled trees) along waterways.

Speaking of muskrats, Paulette Freedman will lead a Fledgling program this Friday (22 Nov) at 10:30AM with a focus on muskrats and cattails.  Age range for this is 2 to 5 year olds and will be held in the ARNWR Visitors Center.


See you on the Refuge.
