Dave, there will probably be a bumper crop of fresh
monarchs arriving really early this year (early-mid May)
in the northern latitudes like Quebec followed by even
larger 2nd generation numbers in late June and early
July.

But then I'd be concerned that the late summer migratory
  generation of monarchs might be deminished
due to a build up of summer parasitic fly and
egg/caterpillar predator bug populations which MAY
follow warm winters and springs.

It will be interesting to see how this all plays out.
If the parasites and predators do not overwhelm the
monarchs later this summer, then the migratory
population could be bigger than anything we have
seen since 2001.
