Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America freely available. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!

We want to express our gratitude to all who showed their support by making a contribution this year. You can donate to support this project at any time.
