Professor Lincoln P. Brower speaks about the migration of the monarch butterfly.

My dear friend and mentor, Jules Poirier, (search his name and monarch) first showed me about these amazing creatures. His books are seminal on the subject. It is wonderful to see that the research continues. Thank you for sharing.

I will put a milkweek plant just to have a monarch caterpillar

I think that is what he means. There may be non-migrating monarchs in southern Florida. I'm not sure. The "normal" migration route is via land, not across the Gulf of Mexico.

Visiting one of the overwintering groves is a dream destination for me! I have to do it atleast once in my life. :) ... Here's a question, I noticed you said "some of them get all the way to northern Florida". I don't know if you are implying they don't come to south FL? Can you clarify that?
