Staff at Chester Zoo have nicknamed the spider “Wendy” and say it has been noticed in Cheshire following the rising temperatures during our scorching summer

A rare wasp spider has been recorded in Cheshire for the first time – and conservationists say her discovery highlights the need to make space for nature.
The large yellow-and-black spider was spotted during a biodiversity survey of Chester Zoo’s estate and has been confirmed as the first recorded sighting of the species in Cheshire. The discovery was made by Chester Zoo conservationists working with RECORD, Cheshire’s local environmental records centre, was subsequently confirmed by an expert from the British Arachnological Society and was officially announced today.
Rosie Cooper, estate biodiversity assistant, made the discovery. She said: “When go out into the field, it involves a lot of walking, using a mixture of apps, wildlife identifying books and our own knowledge to learn more specifics about the habitats we look after.
“I was looking out for plant species and then I saw this big, stripy, brightly coloured spider. I have what you might call a healthy respect for spiders, so my first thought was ‘woah!’ But now I think it’s really cool to have found her.”

Are wasp spiders dangerous?
Despite their striking yellow-and-black appearance, wasp spiders are not considered dangerous to humans. Their distinctive markings resemble those of a wasp, helping to ward off predators, but they cannot sting.
Although they are not aggressive, they may bite if squeezed or directly threatened. Their venom poses little danger to humans, with bites sometimes compared to a nettle sting and potentially causing a minor local reaction.
Where are wasp spiders found?
Wasp spiders are found across mainland Europe, North Africa and parts of Asia. They are particularly associated with the Mediterranean but were first recorded in Britain near Rye, East Sussex, in 1922.
Initially confined largely to the south coast, they have gradually spread across southern England and are now moving further north and west, with warmer temperatures thought to be contributing to their expansion.

What should you do if you see a wasp spider?
Anyone who encounters a wasp spider is advised to leave it undisturbed, as there is no need to remove or kill it.
Members of the public can also report sightings to the British Arachnological Society’s Spider Recording Scheme, which tracks the species’ spread and helps scientists understand how it is expanding into new areas.
The spider, nicknamed “Wendy” by the zoo team, is among a number of species whose ranges are moving northwards as they respond to a changing climate. Ruby Merriman, Chester Zoo’s Estate Biodiversity Manager, said: “We were really thrilled to find Wendy. She’s a beautiful and fascinating species, and recording a wasp spider in Cheshire for the first time is really exciting.
“Wasp spiders are slowly moving north as their southern ranges in Europe warm too quickly for them to adapt. Some conservation organisations refer to animals driven to migrate by climate change as ‘climate refugees’ – which is a good term. They are moving because of human activity, and we need to make space for them.”
The zoo’s wider estate, which spans 205 hectares, includes wet meadows, ponds, reedbeds, species-rich grasslands, woodlands, orchards and hedgerows, supporting a wide range of wildlife. The zoo estate supports a range of key UK species, including harvest mice, which are listed on the IUCN Red List as Near Threatened, great crested newts and badgers. It is also a nesting site for barn owls and hosts dozens of dragonfly, moth and butterfly species.

Scott Wilson, head of field programmes at Chester Zoo, said: “It’s exciting to see new species like Wendy on site, but her arrival is part of a broader, more worrying trend. Our conservationists work across the world, and we are witnessing the impacts of climate change in real time, from droughts in Chile to floods in Indonesia. It is a major threat to biodiversity.
“When mountain snows thaw unseasonably, montane forests dry out and small islands face rising sea levels, the species that depend on them must disperse or die. There is a causal link between habitat loss and climate change, and both are already driving species to extinction.
“European spiders are among many species finding it harder to persist in their traditional ranges as the climate shifts. Wendy is a reminder UK biodiversity is not immune to this.”
