Background Info

  • The Large Tortoiseshell butterfly (Nymphalis polychloros), previously classified as regionally extinct in the United Kingdom, has been re-designated by Butterfly Conservation as a resident breeding species following confirmed sightings across southern England in March 2026.
  • Recent confirmed sightings occurred in Kent, Sussex, Hampshire, the Isle of Wight, Dorset, and Cornwall between late February 2026 and March 10, 2026.
  • The first recorded sighting for the 2026 season took place on February 24, 2026, on the Isle of Wight.
  • Approximately 20 individual sightings were reported within a few days leading up to March 10, 2026, marking a significant increase from the rare, sporadic observations recorded in previous years.
  • The species was last recorded as a breeding population in the UK during the 1980s, having disappeared after being widespread across England and Wales.
  • Historical decline is attributed primarily to Dutch elm disease, which devastated the elm trees that serve as the primary host plant for the butterfly’s eggs.
  • Professor Richard Fox, Head of Science at Butterfly Conservation, stated on March 10, 2026: “We don’t know why the butterfly was lost from Britain, so it’s difficult to know why it has come back as well, but it’s likely to be the climate that is pushing those increased numbers across its European range and we are benefitting.”
  • Professor Richard Fox further noted on March 11, 2026 regarding the potential status change: “I would imagine that, if things carry on with this trajectory, then when we compile our next GB Red List we not classify the Large Tortoiseshell as regionally extinct. I think it’s reasonable to assume that the species is now established in several parts of Britain.”
  • Experts suggest the resurgence is linked to climate change facilitating the expansion of the species’ range from Europe, where populations have thrived, particularly in the Netherlands.
  • One specific observation involved Trevor Collett, a conservationist from Surrey, who drove over 90 minutes to Ashford, Kent, and spent five hours trekking before locating an individual in woodland; he observed the butterfly for 15 minutes before it departed.
  • The butterfly species overwinters as an adult and typically emerges from hibernation in spring, coinciding with the timing of the recent reports.
  • Butterfly Conservation added the species to its First Sightings web page in late February 2026 to track the influx of reports.
  • While the species is currently considered a resident breeder again, Professor Richard Fox described the situation on March 11, 2026, as a “wait-and-see phase,” noting that newly colonizing species may either become common or remain highly localized and potentially disappear again.
  • The re-establishment of the Large Tortoiseshell represents a notable conservation success story occurring amidst a broader trend of declining butterfly populations in the UK.
