The Definitive List of UK Spiders

It’s about time I discussed the creepy crawlies that litter Britain.

Did you know, that the UK is home to over 650 species of spider? And guess what, they all bite!

Reports claimed that last Autumn, spiders ‘the size of mice’ were stated to be invading British homes.

Luckily, autumn is behind us, so you’ll be glad to know that these critters won’t be as common now.

With that in mind, here is a list of 10 common British spiders you may run into during the autumn months. Hopefully, this will help you identify them before they send you running!

Labyrinth Spider

Labyrinth Spider

The Labyrinth Spider is larger than most. It can grow upwards of 18mm long. Found in Wales and England, amongst hedgerows and long grass, the Labyrinth Spider is most common between June and October. Surviving on a diet of small insects and flies, the spider get its name from catching insects in long funnel-shaped webs, which can become very thick.

The female won’t abandon her young until they are ready to leave the web. Once she dies, the young will eat her. This spider is not to be confused with the far more dangerous Funnel Web Spider.

Cucumber Spider

Cucumber Spider
With a name like that, you’d imagine these are harmless, right?

Well, you’re right. They pretty much are. This green spider is seen from April to October and is around 4mm-6mm long. Usually found in gardens, hanging from plants, the Cucumber Spider spends its time eating small insects. These spiders are native to the UK and may look mostly green but they have a small red dot above their spinners on their tail.

Cave Spider

There are two types of this spider, the Meta Menardi and the Meta Bourneti.

Cave Spider

These spiders are around 10-15mm long and are commonly found in the UK throughout the year.

Surviving on a diet of flies, woodlice and other small insects, this spider keeps itself to itself, hiding in caves, tunnels and places with little to no sunlight.

Their eggs are tear-shaped and hang upside down on a silk thread. The young spiders are attracted to sunlight at first, so they’ll seek to find somewhere new to populate. Adult spiders, however, tend to remain in darkness.

False Widow Spiders

False Widow Spider
These infamous arachnids were thought to have arrived in Devon around 1879 from the Canary Islands.

Coming in a 7-14mm shiny black body, with pale markings on their stomachs, these spiders feast on flies and other small insects. Their web formation is very scatty and their silk strands can be found all year round. The name, ‘False Widow’, comes from the fact that they’re often mistaken for the dangerous Black Widow spider. Though their bite isn’t nearly as deadly, they do come from the same arachnid family.

Green Huntsman Spider

Green Huntsman Spider
It’s not commonly known, but Britain has its own version of the infamously terrifying Huntsman Spider. Ours is known as the Green Huntsman. Luckily, this spider is very rare and is only a mere 15mm in comparison to the much larger and daunting 30cm figure of the Huntsman Spider.

The Green Huntsman gets its name from its hunting method; it camouflages itself within green shrubbery before pouncing on its prey of small insects. This spider can be found in woodland areas, parks and anywhere mossy and green.

Black Lace Weaver Spider

Black Lace Weaver Spider

This spider is often found underneath stones and logs in British gardens throughout the year. It has a large, fat, round body with yellow and brown patches on its stomach. Measuring in at around 15mm, its eggs are diamond white and the females are usually found guarding them.

Jumping Spider

Jumping Spider

This eight-legged menace has 340 degree vision and is capable of leaping distances more than 40 times its own body length. They come in a range of colours, including brown with black markings. The picture conveys a bold red and black colour scheme. However, despite their scary appearance, these spiders are not poisonous.

Buzzing Spider

Buzzing Spider Found in many parts of the UK, these spiders are usually discovered in large numbers – especially around April and October.

Much like the Huntsman, they prefer to chase their prey rather than trap them in a web.


Running Crab Spider

Running Crab Spider When it comes to the Running Crab Spider, males and females are separated in appearance. The male spiders adopt a black body and heady, while the female spiders adopt a beige appearance.

These spiders are found in both England and Wales. They commonly reside in grassy areas and low growing vegetation. At 5mm, these spiders are small. They eat a meagre diet of insects and catch them by chasing them down and ensnaring them in a web.

Giant House Spider

Giant House Spider

Measuring at a whopping 120mm, this is the most common spider you’re likely to find in your house. They’re very fast over a short distance but rapidly run out of energy. These spiders build large sheet-like webs and are usually found in the darker corners of your house.

These spiders’ bites do contain venom, though you’ll be very glad to know that they do not usually pose a threat to humans.

Money Spider

money spider amesThese spiders are one of the most common groups in Britain, with thousands of species in it. These fall within the smaller spider category, coming in at 5mm long, they’re very easy to miss, unlike much larger spiders such as the Cardinal Spider.

They get their interesting name from fairy tales and folklore. People used to believe that if you got one of these spiders caught within your hair, it would bring you good look and fortune.

These spiders are harmless to humans and are not aggressive in nature.

Spiders on YouTube

There are many videos on YouTube that dive into the world of spiders, one of our favourites is Levkin’s 10 Most Common Spiders in the UK.

In his video, Levkin goes into detail about the types of spiders that are commonly found in the UK. Many of them pose no threat to humans, but we wouldn’t advise that you go poking around the gardens irritating them!

Honourable Mention

The Cardinal Spider

The Cardinal Spider The Cardinal Spider will grow 20mm on average, which is daunting in itself. However, these spiders are not aggressive, nor are they dangerous. The name comes from the rumour that Cardinal Thomas Woolsey was terrified by this species at Hampton Court back in the 16th century.

Although thought to be harmless to humans, their size and generally sinister look grants them a bad reputation. Bites from these are rare and painless, so don’t worry!

That completes my list for the most common and well-known spiders in the UK. Are there any arachnids that I’ve missed? Maybe you’ve run into a couple of spiders not mentioned on this list, let me know in the comments below!

  1. Hi. I tried to get some more info about Buzzing spider, and noticed that photo do not match. What species of spider is on that photo? I wanted to get more info on that one as well.
    Thanks to this list i managed to identify two spiders I never before meet in my garden: False black widow and Cave spider.

  2. Hi Bogdan, thanks for getting in touch!

    Both the Buzzing Spider and the Jumping Spider are on there, we’ve changed the formatting of the document in case some browsers mix-up the pictures and descriptions.

    You’ve found some pretty interesting spiders in your garden by the sounds of it!

  3. I’ve had two spiders recently like I’ve never seen before. They are medium sized, quite ‘chunky’ long bodies, and they are red. I live in west Wales. Any ideas?

  4. When I lived in the Midlands we often saw what I thought was a spider, it had a tiny round body like the head of a pin and long legs, it lifted its body up off the ground and moved with bent legs. It’s legs were similar to a cellar spider. I can’t find it in any lists of spiders so I am assuming it isn’t one.

  5. Ive seen alot of red orange spiders under logs and slabs body about 1 cm.As a child i never saw one even tho i was always lifting up things looking for it a new invasive species?

  6. OMG! I just saw the biggest spider in my kitchen. It freaked me out as I hate spiders anyway. I thought it was one of those black widow poisonous things but looking at your list I can see it’s a giant house spider. It’s still scary but at least they’re not dangerous! Thanks for this blog I don’t know what I would have done if it was a widow. You hear so many stories but anyway. Thanks again!

  7. Hello Wendy, thanks you for the comment. Hmm red chunky spider eh. It sounds like it could be the Woodlouse spider these are quite common in Wales. If it is the Woodlouse, don’t worry even though they have large fangs they’re harmless to humans. If it was bright red it could have been the jumping spider, which you can see in the photo above. Hope this might help some!

  8. Hello, well, it could be a number of different spiders. You might be surprised to know that there are many red/orange spiders across the globe and even a few in the UK. The woodlouse spider, the dwarf/money spider and the pumpkin spider have been sighted across the UK all of which do live in these mossy areas. Without seeing a picture of the spider, I wouldn’t be able to identify it unfortunately! Though, all three of these spiders are harmless to humans, the woodlouse spider can give you a bit of a bite but it’s not venomous, so you need not worry!

  9. What about the money spider. I’ve been told that its the most poisones spider in the world as it goes for venom, but due to the size of fangs they can not puncture human skin. Any thoughts on this please.

  10. Hi, I saw this yellow and black striped spider with striped legs as well!! this evening. It was on some long grass in a field and I thought it might be a yellow garden spider but the markings are quite different to the pictures . Could you tell me what it is please? I can send a picture if you’d like.

  11. Hello Indra,

    How strange! Yellow garden spiders are not commonly found in the UK, they’re usually spotted in American states, such as Hawaii, Mexico and other parts of Central America. Orb-weaver Spiders are usually mistaken for Yellow Garden Spiders, so you may have seen one of these! Feel free to send us a picture, and I’ll be happy to identify it!

  12. Hello Dean,

    Money spiders do produce bites that can cause swelling and redness, but they are by no means the most poisonous in the UK! Similarly, many people believe that Daddy Long Legs are incredibly venomous, but this is just a myth. They do bite, and the venom stings for a few seconds, but that’s all!
