Insects have declined by 75% in the past 50 years – and the consequences may soon be catastrophic. Biologist Dave Goulson reveals the vital services they perform
I have been fascinated by insects all my life. One of my earliest memories is of finding, at the age of five or six, some stripy yellow-and-black caterpillars feeding on weeds in the school playground. I put them in my empty lunchbox, and took them home. Eventually they transformed into handsome magenta and black moths. This seemed like magic to me – and still does. I was hooked. Continue reading
We feature monarch butterflies in our pages to highlight conservation challenges, and milkweed is often part of the story. Claire Fahy’s story below reminds me that the link between the insect and the plant, and the effort in California to repair that link, is one example of why we created, and why I continue to post on, this platform. A short statement of purpose might be something like: in hope there is meaning. June 15 will mark the 10th anniversary of the first post, and I intend to start the next decade with a more regular series on our regeneration efforts on a few acres of land here in Costa Rica. Because it provides a sense of meaning, among other reasons. So we thank those in California who are doing the same on a 200x scale:
A coalition of conservation groups have partnered with the state to add 30,000 milkweed plants in an attempt to restore the species’ population.
Known for their windowpane wing design and bright orange color, Western monarch butterflies add a dash of magic to the California coast, where they spend the winter. Now a coalition of conservation groups, the California Department of Fish and Wildlife, and the environmentalist organization River Partners are working together to extend a lifeline to the monarchs, whose population has been dwindling drastically.
The groups have embarked on an effort to add 30,000 milkweed plants across the state to provide the butterflies with places to breed and acquire the sustenance for migration.
The Western monarchs’ California population has fallen 99 percent since the 1980s, The San Francisco Chronicle reported. A major factor in that drop has been a decline in milkweed caused by farming and pesticide use. Milkweed is vital to monarchs as a place to lay eggs and as a food source for their caterpillars.

We have featured the plight of monarch butterflies plenty of times on this platform. And bicycle travelogues feature, together with bicycle activism, even more frequently. Today, at the intersection of butterflies and bicycles, we thank Sara Dykman for writing and Smithsonian for publishing this travel-with-a-cause story:
I set off to be the first person to cycle alongside the butterflies to raise awareness of their alarming decline
The idea to bike from Mexico to Canada and back with the migrating monarch butterflies arose from a simple wish to visit them. In 2013, crossing Mexico by bike for the first time, a friend and I entertained the idea of visiting the monarchs at their overwintering sites. Because it was April and the monarchs had already begun migrating north, we decided to forego the side trip.
I spent the next few years idly daydreaming about returning. Continue reading
Just for the beauty of the photographs, this is worth a visit. But there is also an audio accompaniment, allowing you to hear the butterflies. The story of the challenge their habitat faces is, like so many other stories we encounter, painful to read. But there is hope as well:
Environmental destruction and violence threaten one of the world’s most extraordinary insect migrations.
Every November, around the Day of the Dead, millions of monarch butterflies descend on a forest of oyamel firs in the mountains of central Mexico. The butterflies have never seen the forest before, but they know—perhaps through an inner compass—that this is where they belong. They leave Canada and the northeastern United States in late summer and fly for two months, as far as three thousand miles south and west across the continent. The journey is the most evolutionarily advanced migration of any known butterfly, perhaps of any known insect. Continue reading
Today’s post is a finding from the natural world that intersects with the premise of a favored book for kids:
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
Milkweed was first mentioned in these pages so long ago I had forgotten their importance to Monarch butterflies, a seemingly perennial topic for our contributors. So thanks to Margaret Renkl for keeping that tradition going in her Monday op-ed, and reminding us in the process that while it is not all good news out there, it is also not all bad news:
NASHVILLE — I was pretty proud of myself the spring I planted my first organic garden. It was the mid-1980s, and I was a first-year graduate student in creative writing, a program entirely unrelated to horticultural mastery. 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.
At my house, companion planting — marigolds in between the broccoli, tomato vines encircling the spinach — would repel bugs the natural way. 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
Thanks to Janet Marinelli and the team at YaleEnvironment360:
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
