Rare beetle found again in Wales after nearly 60 years

HUMANE WORLD

The short-necked oil beetle, which secretes a yellow-orange oil from its knee joints when alarmed, has been rediscovered at Castlemartin Range in Pembrokeshire. Surveys in 2022 and 2025 found only dead adults; this year’s larvae suggest it is breeding again. Only about one in 10,000 larvae reaches adulthood.
