2026, a good year for butterflies and swifts
The Butterfly Survey Group recorded 18 species this summer, the most since counts began in 2023. The star was the clouded yellow, a migrant from southern Europe: we counted 23, where we used to see one or two.
Swifts did well too. Our volunteers found 120 occupied nest sites across Swanage and Purbeck, and nest boxes are working. Swanage itself went from 28 to 36 occupied sites.
- 18butterfly species, the most since 2023

- 26swift boxes in use, up from 12
Autumn and winter are the best time to put up a swift box, so it’s ready when the birds return in May. Email swiftresearch67@gmail.com and we’ll talk it through with you.
