Ultra-Rare ‘White‑Knuckled’ Wolf Spider Rediscovered on Isle of Wight After 40 Years

Targeted habitat work at Newtown National Nature Reserve is credited with enabling the find.

Overview

  • The species, Aulonia albimana, was recorded in the UK for the first time since 1985 after fears it had been lost nationally.
  • Entomologists Mark Telfer and Graeme Lyons located the spider during a four-hour survey window, finding specimens minutes before their departure.
  • The individuals were discovered in a remote, overgrown area accessible only by boat and about 2km from the species’ former colony.
  • National Trust management under a Natural England programme used Hebridean sheep to restore open, sunlit turf favored by the spider.
  • The rediscovery produced the first digital photographs of the species in the UK, with the British Arachnological Society praising the significance.
