Migration strategies

[Ron Gatrelle]

I sent up a couple of other posts on this (and other matters) but they =
have not made it through the Leps-l data cruncher. It would not surprise =
me if this one did not make it either. My email always works fine with =
everyone else - but I go through periods where I can get nothing up on =
Leps-l.=20
 
My statement is largely one of semantics. Migration vs dispersion =
patterns, and how does one defines a strategy. It is now time for me to =
migrate to bed.

  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.
