Re: [TILS] Cloak habitats

Yup, I too am skeptical of migrating rapae and 'philodice' (here in the west it is eriphyle). I have seen at least one population
explosion of rapae and a few years ago I saw my first and so far only mass movement of eriphyle but nothing that shows migration.
I even recall some literature suggesting Pyrgus communis migrates but again have not seen any evidence of that either.

That Shannon paper is very interesting.  I grew up on Long Island and spent many later years visiting family back there.  Shannon's observations were a few miles west of the beaches I spent many years enjoying.  I can corroborate his observations regarding D. plexippus and P. interrogationis.  Reportedly the Vanessas and J. coenia migrate but I've never seen them migrating south.  I do question things like P. rapae and C. philodice migrating.  Never seen this.  They do explode in numbers along the coast in September but are quite sedentary.  The persistent shore wind can blow them around but they are mostly hunkered down on windy days.  The odd one out is P. sennae.  They head north at breakneck speed in September, certainly to a frozen doom up north.

The flight behaviour of presumed southward migrating cloaks in eastern Canada was described in Gibo 1981 (attached). Presumed migrating cloaks on Long island, NY (and many other species) are described by Shannon 1917 (attached). Very weak documentation, and there is apparently nothing else.

Yes, I recall from past literature review that there is substantial variation in the way that people apply the

word 'migration'; thus making it unclear just what the story really is. I don't recall seeing any evidence for our

North American Cloaks engaging in migration as defined by long distance annual unidirectional movements.
But in Europe there has been documentation of the real Cloaks having irregular mass movements over distance; 

which I do not consider to be migration.

I have only ever found Cloaks in mature deciduous forest in the east, though twice I found larvae on Salix nigra in open, shrubby habitats.


There are many reports along the southern New England shoreline of migratory movement of Cloaks toward the south and west when the Monarchs are migrating.  I have not seen this and it may be a localized movement.  I have, however, witnessed Polygonia interrogationis migrating along the shoreline and P. comma migrating south overland.  These also may be localized movements, as both do hibernate here.

Prior to August 2005 I had found Nymphalis antiopa hyperborea in a variety of upland forest habitats and even in bits of riparian woodland/willow shrubbery of the North American prairie region. In August 2005 Ken Philip took Joe and I to the Bonanaza Creek bog near Fairbanks for some butterfly fun and there I was able to add spruce bog to the list of habitats used by Cloaks. Here are some pics; the sky was murky due to forest fire smoke
