The Breathing Spaces wildlife area at Horsey Windpump has enticed the tiny predator, which combines arachnid legs with a wasp-coloured body, to make only its fourth recorded visit to the region.
Female members of the species are usually larger, and often eat their male conquests after mating. They thrive in areas of short grass and devour beetles, winged insects and grasshoppers, although their bite is not poisonous.
Their sighting could signify the increasing exoticism of the domestic climate, as Wasp Spiders have traditionally favoured the south coast since being discovered in the 1920s.
Scientists predict the imminent start of the spider mating season will result in more Wasp Spider outings, but their east coast appearance represents a triumph for organisers at the Grade II-listed Windpump.
"They're absolutely gorgeous creatures and it just goes to show that anything can turn up if you create a flower-rich area like this," said Warden Stephen Prowse, who has overseen the wildflower meadow, traditional orchard and sensory garden since they were added in 2008.
"It's a credit to the volunteers who have created this wonderful wildlife area and I really hope that people will continue to enjoy and look after our new wildlife while visiting the Windpump."
The five-storey centre has already hosted 25 species of butterfly and a wide range of other insects, as well as barn owls, grass snakes and Chinese water deer.
