Migration strategies

[Cris Guppy or Aud Fischer]

Ron is incorrect that D. plexippus is the only one of the listed species =
with "migration strategies", assuming that all migratory species have =
"migration strategies". And few migrations are well documented.
 
Most of the species listed I have no experience with. However, In BC Red =
Admirals, California Tortoiseshells and West Coast Ladies migrate in =
from the south each year, with only a couple records of each apparently =
successful overwintering on the south coast of BC (no return migration =
documented). The Painted Lady definitely migrates north to Canada from =
extreme southern USA and Mexico each year (no return migration =
documented). Orange Sulphurs (C. eurytheme) migrate north each year (no =
documented return migration). Mourning Cloaks have a southward migration =
from eastern Canada in the fall (no migration documented in western =
North America), and migration in Europe is well documented.. And there =
are altitudinal migrations (up to high elevations during summer, =
returning to low elevations in the fall) of a wide variety of species. =
There is a very large literature on migration by many species of =
butterflies. I suggest a search using Biological Abstracts (at a =
University), and the library catalogue of a good University.

  Of the species you list, the only one with _migration strategies_ is =
D. plexippus and then not all subspecies.

    Dear List Members,=20
    I would appreciate any information you could give me concerning the =
migration strategies of any of the following butterflies:  Red Admiral =
(Vanessa atalanta), Painted Lady (Vanessa cardui), Common Buckeye =
(Junonia coenia), Question Mark (Polygonia interrogationis), Eastern =
Comma (Polygonia comma), and any others excluding the Monoarch (Danaus =
plexippus).  I'm interested in things like where they overwinter, =
overwintering diapause stage, geographical range (countries), etc.  =
Thanks in advance.
