Monarch Butterfly Migration Film
This will be neat to see. It is one of the great migrations in the world and perhaps one of the most unlikeliest. I grew up with them and even collected pupae to watch them emerge.
A real surprise is that a tagged butterfly from Wisconsin made it all the way down to Mexico in one generation. These are amazingly, generational migrations.
Fears about this butterflies future are likely misplaced now that the winter refugia is well known and the insects have zero economic value.
However poaching suggests that landholder are uncompensated and need to be bought out. Do that and establish a conservatory and the problems will go away.
At the same time, the milk weed needs to be cultivated for its natural product stream anyway.
