Thank you for all you do throughout the year to protect the invertebrates in your community. The end of the year is just a few days away and we hope you will consider making a tax-deductible donation to Xerces in 2025.

From monarchs and bumble bees to fireflies and freshwater mussels, we are working to make a difference for the animals that capture your imagination—but we need your support to be successful.  

If you are able, please consider making a tax-deductible, year-end gift today! Gifts can be received online before midnight Eastern Time on December 31st.

If you have already given, THANK YOU for your support!

Important new USPS information for mailed gifts:

USPS has a new rule for postmarking envelopes, which means that your envelope could be postmarked later than the day that you mailed it. To ensure 2025 postmarking, please bring your envelope to a USPS counter before close of business on December 31 and ask the representative to postmark it that day.

Your tax-deductible donation will help grow and sustain that essential work.
