How can we help protect monarch butterflies?
Every year, monarch butterflies fly south for winter—sometimes traveling up to 1,800 miles.

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. So when we talk about losing the monarch butterfly, we're really talking about losing that migratory phenomenon.
And when we have a low population year, one of the things that we see as the cause is often not enough food during the migration to sustain the adults making that journey, adult monarch butterflies drink nectar from flowers like lots of pollinators. Female monarchs will only lay eggs on milkweed plants. The babies are caterpillars, and they will only eat milkweed.
Overall, one of the drivers of the 80% decline in eastern monarch butterfly populations is loss of milkweed on the landscape. When we do good monarch conservation, we're sustaining lots of other insects because we need to be planting blooming flowers throughout the season and we need to be planting milkweed unlike a lot of really big conservation stories. There are things that we can do on the ground in our communities that are really impactful.
A lot of the landscape is residential yards. The largest irrigated crop in the United States is turf grass. It's not doing a lot for us except giving us yard work. Planting native flowers that have not been sprayed with pesticides are very effective at conservation for monarch butterflies and for other pollinators, and specifically planting milkweeds that are native to your region and having those available during the monarch breeding season.
So I encourage people to plant native plants in their garden to benefit insects. You know, you don't have to be somebody with a huge backyard to do this, but you can be part of a, you know, thousand mile migration. Ah and that's pretty cool.
