The first, early-season, part of the count ended on Nov 2. So far, we estimate ~5,000 monarchs, with data still coming in. That's fewer than at the same time last year, but we suspect that Oct weather has delayed many butterflies, & more will be arriving soon!

This is one of the nonprofits we donate to. It's the leading advocate for pollinators and other invertebrates, which are so crucial to the health of our ecosystems. Xerces provides a wealth of resources on habitat protection for farmers, landowners, park managers, and homeowners. Highly recommended.
The threats facing invertebrates are serious, & not going away without hard work. Whether you've supported Xerces for 25 years or are new to the team, please consider making a donation to today, so we can continue protecting invertebrates & the places they need to thrive in 2026. ➡️ xerces.org/give

Why do cows and bees both want native plants? We made a guide with all the facts. The rangelands we use for livestock can also be home to native wildflowers, shrubs, & of course pollinators!

From #herps to #insects, #birds, & #mammals, the leaf layer is more than just nature’s carpet - it’s a sanctuary, food source, & protective shield. These critically important pieces of microhabitat are entirely removed when we throw away our yard leaves. #LeaveTheLeaves

When you support Xerces, you are directly contributing to building more pollinator habitat, reducing pesticide use, surveying for rare species, helping people everywhere learn about invertebrates, & more. From the bugs (and us) to you, THANK YOU! 💖🦋

Good news: the bugs that eat pests in your yard also use fallen leaves to survive the winter!
In general, leaving leaves where they fall is the right move. But there are a few situations where removing (or just moving) plant material from your yard is the right move ⤵️

In 2024, we built pollinator habitat on farms, developed new firefly sanctuaries, gave away over 145k native plants, helped pass laws regulating pesticides & expanding state conservation programs, & so much more. All of this is thanks to your support!

One of the most valuable ways to support pollinators and other invertebrates is to provide them with the shelter they need to survive the winter. Thankfully, all you need to do is do less yard work.
