Borboleta-Branca da Madeira
The Borboleta-Branca da Madeira: The Story of Madeira’s Lost Butterfly
Madeira once hosted a truly unique butterfly known locally as the Borboleta-Branca da Madeira — the Madeiran large white (Pieris wollastoni). This butterfly was endemic to Madeira Island, found nowhere else in the world. Sadly, it was recently declared officially extinct, marking a significant moment in European natural history.
A Distinctive Madeira Native
The Borboleta-Branca da Madeira was a large, striking butterfly in the Pieridae family. Adults had predominantly white wings with black tips on the forewings and small black markings on the hindwings. Females showed additional black spots on the upper side of the front wings. Its wingspan measured approximately 55–72 mm, making it noticeably larger than many common butterflies.
Larvae were green with black lumps and yellow stripes. They fed on plants in the cabbage family, such as nasturtium and cabbage, and completed multiple generations a year. The butterfly primarily occurred in Madeira’s laurel forests (Laurisilva), a lush, misty habitat in the island’s interior and northern slopes.
From Common to Lost: Decline and Extinction
The Borboleta-Branca was once widespread across Madeira, including higher altitudes above 650 m, where humid laurel forests flourished. Over time, however, its numbers dwindled sharply. The last confirmed sightings occurred in 1977, and extensive surveys throughout subsequent decades failed to locate any individuals.
In 2025, the International Union for Conservation of Nature (IUCN) formally declared the species globally extinct, making it the first butterfly in Europe to receive that classification. This announcement underscored the fragility of island ecosystems and the long-term effects of habitat loss and ecological change.
Researchers and conservationists suspect several factors contributed to the decline, including habitat degradation in laurel forests and competition or disease introductions from non-native butterflies like the small white (Pieris rapae), which may have altered disease dynamics or resource availability.
Madeira’s Butterfly Conservation Efforts Today
Though the Borboleta-Branca is gone, Madeira still hosts other endemic butterflies at risk. These include the Madeiran brimstone (Gonepteryx maderensis) and the Madeiran speckled wood (Pararge xiphia), both considered endangered due to limited habitat and competition.
The EU-funded LIFE4BEST project supports conservation work for Madeira’s remaining endemic species. Efforts include habitat mapping, monitoring populations, educational outreach and planning for long-term survival of endangered butterflies.

What This Loss Teaches Us
The extinction of the Borboleta-Branca da Madeira highlights the vulnerability of island endemics to environmental change. Habitat loss, invasive species, disease and human influence can swiftly erase species found nowhere else. The butterfly’s disappearance is a poignant reminder that biodiversity requires proactive protection.
Visitors to Madeira can still appreciate the island’s rich natural heritage by exploring the UNESCO-listed Laurisilva forests, birdwatching local species or learning about conservation programs protecting butterflies that remain.
Madeira’s lost butterfly may no longer flutter through the laurel shadows, but its story continues to inspire stewardship and awareness of fragile ecosystems.
