New Cretan Moth Species Named After Pope Leo XIV Highlights Ongoing Biodiversity Gaps

Discovery of the “Pope Leo” Moth
Researchers identified a previously undocumented moth on Crete’s White Mountains (Lefka Ori). The species, Pyralis papaleonei, was collected mainly at the Omalos plateau between 1,000 m and 1,200 m elevation. Adults were captured at light traps in June, with a single specimen recorded in October, suggesting either an extended flight period or a second generation. The description was published on 28 April 2026 in the open-access journal *Nota Lepidopterologica*.
Taxonomic Context and Distinguishing Features
*P. papaleonei* belongs to the Pyralis regalis species group, a lineage noted for vivid coloration and regal nomenclature (e.g., *P. regalis*, *P. princeps*, *P. cardinalis*). Morphologically, the moth displays a 2 cm wingspan, purple-violet forewings with a narrow white band, a large orange-gold spot, and pale gray-purple hindwings divided by two jagged white lines. Male and female genitalia possess unique structures, including a sclerotized signum in females absent from close relatives.
Genetic barcoding of 38 new samples alongside 90 existing sequences revealed a minimum 5.78 % divergence from the nearest *P. kacheticalis* cluster and 9.4 % divergence from *P. regalis*, exceeding typical species-level thresholds.
Researchers and Institutional Collaboration
The study was led by Peter Huemer (Tyrolean State Museum Ferdinandeum, Innsbruck) and involved scientists from the Finnish Museum of Natural History and the Bavarian State Collection of Zoology. Peter Heumer, former head of natural-science collections at the Tyrolean State Museum, contributed to the analysis and interpretation.
Data & Statistics
- Wingspan: ~2 cm (?0.75 in)
- Elevation of collection sites: 1,000–1,200 m
- Specimens examined: ~45 individuals of the new species, ~55 of related taxa
- Genetic distance to nearest relative: 5.78 % (to *P. kacheticalis*)
- Endemic status: known only from the White Mountains of western Crete
- Proportion of Crete’s endemic Lepidoptera described since 2000: 40 % of 76 species
Significance for Conservation and Biodiversity
The naming honors Pope Leo XIV, whose public advocacy for climate and environmental protection is cited as a symbolic link between scientific discovery and broader ecological stewardship. The authors argue that formally recognizing species is a prerequisite for effective conservation, especially amid a global biodiversity crisis. The find also underscores that even well-studied European faunas retain undocumented diversity, reinforcing the need for continued taxonomic surveys.
Official Statements & Responses
The study’s authors highlighted the Pope’s role as a “strong advocate of climate and environmental protection,” hoping his voice would inspire humanity. They emphasized that the discovery illustrates how many species remain undescribed, limiting conservation planning. Pope Leo XIV’s remarks at a recent global church summit called for a societal shift “from collecting data to caring, and from environmental discourse to an ecological conversion that transforms both personal and communal lifestyles.”
Conflicting Reports & Gaps
Sources differ slightly on the reported genetic divergence: one describes “about six percent,” while another specifies “5.78 %.” A typographical error refers to the insect as the “Pope Lion moth” in one Italian outlet. Critical ecological data—host plant, larval stages, and full distribution—remain unknown, limiting assessments of vulnerability.
Verbatim Quotes
- “The Pontiff is a strong advocate of climate and environmental protection, and we hope that his voice may serve as an example for humanity,” — Study authors
- “He says: “We are facing a global biodiversity crisis, yet only a fraction of the world’s species has been scientifically documented.” — Peter Heumer, former head of natural-science collections, Tyrolean State Museum
- “from collecting data to caring, and from environmental discourse to an ecological conversion that transforms both personal and communal lifestyles.” — Pope Leo XIV (global church summit)
- “Effective conservation of biodiversity requires that species are first recognized, described, and named.” — Peter Huemer, lead author
What’s Next
The authors recommend expanded field sampling in Crete’s mountainous habitats and integrative taxonomic work on the *Pyralis* complex, including genetically distinct populations in China and unresolved variation within *P. kacheticalis*. Publication of the findings in *Nota Lepidopterologica* provides a baseline for future ecological and conservation studies of this endemic moth.
