What to know

  • The short-necked oil beetle, a nationally rare species nearly extinct in Britain due to habitat loss, has been rediscovered breeding in Wales at Castlemartin range after nearly 60 years.
  • A 2026 survey found larvae that suggest successful reproduction, reversing concerns after 2022 and 2025 surveys found only dead adults.
  • The beetle depends on solitary bees and dense vegetation; it uses larvae with hook-like feet to hitchhike on bees to their nests, where they feed on pollen.
  • The species is part of a broader habitat recovery effort in Wales involving multiple endangered species that share similar ecological needs.

“We are very grateful to our partners and volunteers for persevering with us after two years without larval sightings and look forward to the continued management of the site so that this amazing species can survive now and into the future.”

    2026 survey discovers breeding larvae at Castlemartin

    A 2026 survey discovers larvae distributed in a pattern suggesting hatchlings from a larger batch of immature beetles have successfully developed. Natural Resources Wales announces the rediscovery as the first confirmed breeding evidence in nearly 60 years.

    “The short-necked oil beetle is an amazing creature and not only depends on a very specific habitat to survive, but the presence of solitary bees as well.”
    — Anna Hobbs, Bumblebee Conservation Trust

      “The unusual creature relies on solitary bees and thick vegetation and flower coverage to survive. Its larvae have hook-like feet to snag on to bees, and once in their nest, they feed on pollen until ready to emerge as adults, with a lifespan of about a year.” https://www. theguardian.com/environment/20…
