The eastern regal fritillary butterfly is on the brink of extinction. Your voice and action are crucial to saving this rare and irreplaceable species before it’s too late.
The eastern regal fritillary butterfly, once a vibrant presence across the eastern United States, now hovers on the brink of extinction. Its last refuge, a 250-acre preserve within the Fort Indiantown Gap National Guard Training Center in Pennsylvania, is the only place east of the Mississippi River where this species still survives1.
This butterfly, similar in size to the monarch but distinguished by its dark hindwings, depends on a specific habitat for survival. Native violets are the only food source for its caterpillars, while the adult butterflies rely on nectar from various flowers, sometimes traveling up to 100 miles to find it2. The carefully managed grasslands at Fort Indiantown Gap provide the conditions necessary for the butterfly’s life cycle, but even this sanctuary is not immune to the threats that have devastated the fritillary’s population elsewhere.
Threats to Survival
The eastern regal fritillary’s habitat has been dramatically reduced due to agricultural expansion, urban development, and the encroachment of invasive species. Climate change exacerbates these threats by altering the bloom times of violets and other plants crucial to the butterfly’s survival3. The fragile balance at Fort Indiantown Gap is constantly at risk from these environmental changes, making the survival of this butterfly increasingly precarious.
Military activities at the base, while carefully managed to protect the butterflies, also pose risks. Although the base has implemented conservation measures, the presence of military vehicles and training exercises could inadvertently damage the butterfly’s fragile habitat4.
Why Conservation Matters
The eastern regal fritillary is not just a beautiful species on the verge of disappearing; it is a vital part of the ecosystem. Butterflies like the regal fritillary play a critical role as pollinators, and their decline could have cascading effects on the environment. The loss of this species would not only mean the extinction of a unique and irreplaceable butterfly but also a significant blow to the health and diversity of our natural world5.
Recognizing the urgency of the situation, the U.S. Fish and Wildlife Service (USFWS) has proposed listing the eastern regal fritillary as an endangered species under the Endangered Species Act (ESA). This designation would provide the butterfly with the protections and resources needed to prevent further decline and support ongoing conservation efforts6.
Act Now to Protect the Regal Fritillary
Time is running out for the eastern regal fritillary. The public comment period for the USFWS’s proposal is open, and your voice can make a difference. By supporting this proposal and calling for greater conservation efforts, we can help ensure that the last remaining population of this butterfly continues to survive and thrive.
This is not just about saving a single species—it is about preserving the balance of our ecosystems and protecting the natural heritage that sustains us all. The regal fritillary’s story is a powerful reminder of the fragility of life and the importance of taking action before it’s too late.
Join us in the fight to save the eastern regal fritillary. Sign the petition today and help secure a future where this remarkable butterfly can continue to grace our skies.

The Petition:
To the Director of the U.S. Fish and Wildlife Service,
We, the undersigned, wish to express strong support for the U.S. Fish and Wildlife Service’s proposal to list the eastern regal fritillary butterfly as an endangered species under the Endangered Species Act (ESA). This proposal is a critical step toward ensuring the survival of this rare and beautiful species, which is now confined to a single location in the eastern United States—Fort Indiantown Gap in Pennsylvania.
The eastern regal fritillary once flourished across a vast range, but today, its population has dwindled to the brink of extinction. The loss of grassland habitats, combined with the ongoing threats of climate change and habitat fragmentation, has pushed this butterfly to the edge. Without immediate and active conservation measures, we risk losing this species forever.
Listing the eastern regal fritillary as endangered will not only provide it with the legal protections necessary to prevent further decline but also unlock essential resources for habitat restoration and conservation efforts. I urge the U.S. Fish and Wildlife Service to take every possible action to protect and restore the habitats vital to the fritillary's survival, and to support initiatives that promote biodiversity and the health of our ecosystems.
By acting now, we can ensure that future generations will inherit a world where the regal fritillary, and countless other species, continue to thrive. Protecting this butterfly is not just about saving a single species—it is about preserving the delicate balance of nature that sustains us all.
Thank you for your commitment to conservation and for considering the urgent need to protect the eastern regal fritillary.
Sincerely,
