Where is your Mexican village located? Are there monarchs
in England? I think that monarchs and the migration process
is such a fascinating occurrence. About your question....I do
know that monarchs migrate up into Canada, although I don't
know how far up into Canada they go. I was camping up in
northern Minnesota and actually saw monarchs in Thunder
Bay which is an area just on the Canadian side of the border.
The monarch lays its eggs in the summer in Minnesota once
the milkweed has bloomed (which takes a while because it
is so cold). Around July is when I really started to notice
them this summer. I would think that they emerge in Canada
about a month later than they do here, but that's just a guess.
Good Luck on your project.
