Drought-Stricken UK Butterflies Face Population Crash

Despite a record-breaking summer for butterflies in the UK, conservation experts warn of an impending population crash due to drought conditions. The annual Big Butterfly Count recorded its second-highest count on record, with over 101,000 participants spotting nearly 1.4 million butterflies and moths across the country.

The charity behind the count, Butterfly Conservation, is particularly concerned about the impact of this year's drought-stressed caterpillars emerging as adults next year. According to Professor Richard Fox, head of science at Butterfly Conservation, 'this has been one of the hottest, driest summers on record' and the real damage may not be visible until 2027.

Several species saw above-average numbers, with the Painted Lady increasing by 335 per cent compared to last year. However, Professor Fox notes that a good summer for adult butterflies is 'not the same as a good summer for butterfly populations.' He warns of potential disaster if droughts continue, citing the severe impacts on butterfly populations in 1976 and 1995.

Butterfly Conservation is urging the public to help 'drought-proof' their gardens this winter by planting drought-resistant trees and shrubs, setting up water butts to collect rainwater, and leaving patches of grass to grow long. Professor Fox emphasizes that 'with increasingly hot, dry summers and droughts predicted to become more frequent due to climate breakdown, degraded habitats and already depleted butterfly populations, some species may be pushed further and faster towards extinction.'
