Britain’s “Big Butterfly Count” finds the country has a near-record butterfly and moth season, with volunteers tallying almost 1.4 million butterflies and day-flying moths. The results follow a summer of record heat in 2026 and are described as the second-best season for butterflies in the last 16 years.
More than 100,000 volunteers take part in the annual survey, which relies on people counting species in their local areas. Across the season, common butterflies are reported in large numbers, and painted ladies—an often migratory species—show a sharp increase, up about 335% compared with the previous year.
While both outlets highlight the scale of the counts and the unusually warm weather that coincides with more adult insects, they also note potential ecological downsides. Experts cited in the reporting warn that favourable conditions for adult butterflies may not translate into strong survival for caterpillars, with drought-linked impacts expected to affect next year’s caterpillar population through reduced food and suitable conditions.
