New moth species Pyralis papaleonei honors Pope Leo XIV, linking taxonomy, biodiversity conservation, and environmental advocacy.
Newsroom (07/05/2026 Gaudium Press ) A newly identified moth species discovered on the Mediterranean island of Crete has been named Pyralis papaleonei, or the “Papa Leon moth,” in tribute to Pope Leo XIV. The naming reflects not only a scientific milestone but also a symbolic appeal for stronger environmental stewardship.
The species was described in the scientific journal Nota Lepidopterologica by researchers Peter Huemer, Lauri Kaila, and Andreas H. Segerer. The moth is characterized as medium-sized, with a wingspan of approximately 2 centimeters, marked by golden spots and prominent white bands.
In their publication, the authors explained the reasoning behind the name: “The new species is dedicated to the leader of the Catholic Church, Pope Leo XIV. The pontiff is a staunch advocate for climate and environmental protection, and we hope his voice will serve as an example for humanity.”
A Naming Tradition Rooted in Symbolism
The naming of Pyralis papaleonei follows a longstanding tradition within the genus Pyralis, where species are often associated with titles of high rank. Due to its distinctive appearance, the new moth joins a group that includes Pyralis regalis, Pyralis imperialis, Pyralis princeps, and Pyralis cardinalis—names that evoke royal or ecclesiastical status.
According to the Tiroler Landesmuseum Ferdinandeum in Innsbruck, Austria, species are typically named based on physical traits, geographic origin, or to honor notable individuals. However, the Pyralis genus developed a unique naming convention as early as 1775, when Austrian naturalists and Jesuits Michael Denis and Ignaz Schiffermüller introduced Pyralis regalis, inspired by its regal coloration.
This tradition has continued within the superfamily Pyraloidea, a vast group that includes approximately 16,000 described species worldwide.
Taxonomy as a Human Endeavor
The act of naming species carries both scientific and philosophical significance. The museum notes that taxonomy—the classification and naming of organisms—has deep cultural roots, often linked to the biblical account in Genesis 2, where Adam is tasked with naming all living creatures. This connection has led some to regard taxonomy as “humanity’s oldest endeavor in the biblical sense.”
For Huemer, head of studies at the Tyrolean State Museum, naming a species goes beyond classification. It is also a way to communicate values and priorities.
“We are facing a global biodiversity crisis, and yet only a fraction of the world’s species have been scientifically documented,” Huemer stated. “Effective biodiversity conservation requires, first and foremost, that species be recognized, described, and named.”
A Call for Ecological Responsibility
The naming of the Papa Leon moth also serves as a broader call to action. Huemer emphasized that the gesture is intended to encourage the Catholic Church’s leadership to continue highlighting humanity’s responsibility toward environmental preservation.
This message aligns with Pope Leo XIV’s remarks at a 2025 international conference on climate justice, marking the tenth anniversary of Pope Francis’ encyclical Laudato Si’. During the event, the Pope called for a deeper transformation in how individuals and communities approach environmental issues.
“Only by returning to our hearts can a true ecological conversion take place,” he said. “We must move from collecting data to caring, and from environmental rhetoric to an ecological conversion that transforms both personal and communal lifestyles.”
In linking scientific discovery with moral responsibility, Pyralis papaleonei stands as both a contribution to biodiversity knowledge and a symbolic reminder of the urgent need to protect it.
