Help protect the little things that run the world!


Dear Friends,


  • • You can thank an insect pollinator for one out of every three mouthfuls of food that you eat.
  • • Your grilled salmon dinner would have been impossible without the small flies and other aquatic invertebrates that young fish eat.
  • • Ninety-six percent of songbirds rear their young on insects.
  • • In Yellowstone and Glacier national parks, grizzly bears eat up to 40,000 miller moths a day to fatten up for hibernation.


With well over one million known species, insects and other invertebrates eclipse all other forms of life on Earth. They are essential to the reproduction of most flowering plants, including many fruits, vegetables, and nuts that we eat; they are food for birds, fish, and other animals; they filter water and keep our rivers and streams pristine; and they clean up waste from plants and animals.

Although they are indisputably the most important animals on earth, invertebrates are in trouble. One recent review of the science estimated that, if losses continue at current rates, 40% of the world’s insect species may go extinct over the next few decades. There is no time to wait. We need to act now.

Thanks to our donors, Xerces is at the forefront of invertebrate conservation and we have tried-and-true methods to maximize invertebrate diversity across landscapes. Please show us your support by making a tax-deductible donation today.

Large, connected natural lands and freshwater systems act as reservoirs for invertebrate diversity. Protecting these areas is essential, but not enough. We must also address conservation in farmlands and urban areas. Approximately 40% of global land use is devoted to agriculture and 55% of people live in towns and cities, areas where roadsides, parks, and gardens can provide important habitat for insects and other invertebrates

Xerces’ work has led to the protection and restoration of over 2.5 million acres of habitat on farmlands, wildlands, roadsides, and parks. Our advocacy is leading to better management of streams and rivers; protections for the most vulnerable species; improvements to key laws such as the Farm Bill; and changes to how cities, counties, and states regulate pesticides. And through Bee City USA, we now have 150 city and college communities in our network mobilized to protect pollinators.

But, to create the impact needed to make this critical issue a priority in the everyday lives of people around the planet, we need your participation. Please act now.

The good news is that there is hope. Insects are resilient and the steps each of us can take have an immediate and meaningful impact, from planting more flowers and giving up pesticides to encouraging your community to take steps to expand habitat for invertebrates.

This problem is real, the impacts of decline will be devastating, your support is critical. Show us that you are behind us by making a tax-deductible donation to Xerces today!

Thank you for all you do.
