I wonder if the old breeding habitat didn't trigger the generation of a new
Just think, the whole thing could represent the population growth of a few
of the Monarchs you left behind 30 years ago (and maybe a few of their
friends). When the impacted ancestors emerged, they didn't find as much
milkweed as they enjoyed in their youth (O.K., so I'm humanizing them just a
little bit), but they found some great places to hang out.
In actuality, it's probably more analogous to the urbanization of Canada
Geese. No need to migrate so far when there's plenty of great overwintering
habitat in the newly developed city.
I know there's a point in here somewhere, if I could just find it...
