What Very Hungry Caterpillars Really Do

Today’s post is a finding from the natural world that intersects with the premise of a favored book for kids:

Don’t Get Between a Caterpillar and Its Milkweed

Before metamorphosis, monarch butterflies will aggressively head butt each other for access to their favorite food.

In the 1969 children’s book “The Very Hungry Caterpillar,” the tiny protagonist spends a week snarfing his way through a smorgasbord of fruits, meats, sugary desserts and, finally, a nourishing leaf. This family-friendly tale was missing one crucial and far less G-rated plot element: the pure, unadulterated rage of an insect unfed. Continue reading

But I had taken a college course in environmental biology, and I knew the basics: The more chemicals you use in a garden, the more chemicals you’ll need in the garden. It’s a self-perpetuating cycle, more reliable than the seasons.

Any lingering pests would be dispatched by beneficial insects like ladybugs and praying mantises. One evening I watched happily as cabbage white butterflies flitted over silvery broccoli leaves. Those little white butterflies pausing in the gloaming on the water-beaded broccoli made for a tableau of bucolic harmony. Continue reading

Interstate 35, which stretches from Minnesota to Mexico, lies in the heart of the monarchs’ migration route.

Can the Monarch Highway Help Save a Butterfly Under Siege?

The population of North American monarch butterflies has plummeted from 1 billion to 33 million in just two decades. Now, a project is underway to revive the monarch by making an interstate highway the backbone of efforts to restore its dwindling habitat. Continue reading
