“As we were walking up through the heathland, I just noticed this very strange-looking spider,” said Matthew Rigby, who discovered the creature.
He put the photo through an AI app to help identify it, he added.
“I think this is the most excited I’ve been, finding anything on Kinver,” he added.
The British Arachnological Society describes the purseweb spider as “scarce”, external. Most sightings are in the south of England, though there are “scattered outposts” elsewhere, it added.
Kingsford Heath was restored by Worcestershire County Council about two decades ago, with its ongoing management now the responsibility of the National Trust.
The trust said heathland was characterised by wide, open landscape, with scattered trees and low shrubs, such as gorse, heather and grasses.
The sandy soils provide an ideal habitats for lots of invertebrates, including the purseweb spider, they said.
