Britons will vote on their nation's favorite butterfly in the inaugural poll run by Butterfly Conservation, with 60 species on the ballot. The vote runs until 7 June and includes candidates ranging from the small tortoiseshell, a formerly common garden visitor now in rapid decline, to the purple emperor, which poet John Masefield described as an "oakwood haunting thing," and the brimstone, recognized as spring's ultimate herald.
The poll captures a moment of ecological consequence. Britain's butterfly populations face mounting pressure from habitat loss, pesticide use, and climate disruption. The small tortoiseshell exemplifies this crisis. Once abundant across British gardens, the species has collapsed by over 75 percent in the past two decades, according to Butterfly Conservation monitoring data. Disease, particularly a microsporidian infection, combined with loss of breeding plants like nettles, has devastated populations.
The purple emperor represents a different story. This woodland specialist remains relatively stable but depends on pollarded willows found in specific habitat types. Conservation efforts focused on restoring ancient woodland have bolstered some populations in recent years.
The brimstone, with its distinctive pale green wings and early emergence each spring, demonstrates adaptability. Unlike many British butterflies, brimstones survive winter as adults rather than as pupae, allowing them to respond quickly to warming temperatures. This trait has helped maintain populations through recent years of climatic volatility.
Butterfly Conservation's poll serves dual purposes. It engages the public with native biodiversity while generating data on which species Britons value most. Public preference can drive conservation funding and policy attention. The organization uses such information to shape its advocacy campaigns and educational initiatives.
The vote reflects broader ecological anxiety in Britain. Insect declines across the nation have prompted government reviews and conservation pledges. Butterfly monitoring schemes, run by the UK Butterfly Monitoring Scheme
