How to Support Monarch Butterfly Conservation—During Earth Week and Beyond!
Published on April 27, 2019
Helping the monarch back to full health isn’t going to be easy or quick, but we can’t stand by and do nothing. If we all plant a small patch of milkweed and nectar plants, and all think about how we can change our actions to make things better for monarchs, together we can transform the landscape to allow the monarch to rebound—and give our children the gift of watching orange wings flap in the sunshine.

A Shifting Climate Creates Winners and Losers
Published on November 27, 2018
To mitigate the impacts of climate change we need to increase the amount of high-quality and resilient habitat everywhere. Natural areas are the glue that holds all other habitat together, but for insects even small patches in connected networks within agricultural, suburban, urban, and other landscapes can be beneficial. Whether you are a gardener, a farmer, or the manager of a park or nature reserve, you can take action to protect and restore habitat. Xerces has resources to help on our website.

Can Robobees Solve the Pollination Crisis?
Published on September 17, 2018
The problem is more complex than just crops. At least 85 percent of all terrestrial plant species either require or strongly benefit from some form of animal pollination, and the idea of robotic pollinators ignores the many wild plants in meadows, prairies, hedgerows, and forests. Focusing solely on crop pollination and failing to take the pollination of native plants into account may well lead to a deterioration in the plant communities that make up the very fabric of our environment.
Keep Monarchs Wild!
Published on September 11, 2018
Instead of rearing—which is risky and unproven in helping monarchs—we should focus on more effective ways to conserve these glorious wild animals. Our tactics should address the reasons the species is in trouble to begin with. We can do this through taking action to protect natural habitat; to plant native milkweed and flowers; avoid pesticides; support wildlife-friendly, local, and organic agriculture; contribute to research efforts via citizen science; and organize ourselves to push for policy changes.
