The Monarch butterfly population in the U.S. has declined more than 70% in the last 20 years. The reason? Human activity, such as eradicating milkweed (the Monarch’s primary food source) and the use of pesticides along migration routes, plus the effects of climate change.

All across the U.S., citizen scientists are growing milkweed in their yards, attracting butterflies that lay eggs that turn into beautiful caterpillars, that transform in gorgeous butterflies.
