Monarch butterflies are important because of their huge migration.
There is not another butterfly that makes this kind of significant long-distance migration.
This is globally unique and really special.
Hi, I'm Aster Hassell.
I'm a lead conservation ecologist at the Kessler Science Action Center, the Field Museum in Chicago, Illinois.
So we are in the midst of a massive global decline in insect populations.
75% of animals on Earth are insects.
And when there's a global decline in something that's as diverse as insects, we know that there is not one simple cause.
In monarch, butterflies are often really good at bringing together conservation issues because they move across a whole landscape.
You can't protect one place and just have everything that species needs.
