Aliens flood into UK waters
By Rebecca Morelle
Science reporter, BBC News

Exotic species of spiders are making their homes in the UK, scientists say.

Researchers believe arachnids arriving in imports of food and plants are now able to survive and spread thanks to the UK's increasingly mild climate.

The new inhabitants include a species of false widow spider and some believe the deadly black widow could be next to invade.

Conservation group Buglife wants import rules to be strengthened to stem the tide of alien species invasion.

Matt Shardlow, director of Buglife, told BBC News: "Other countries in the world take great care about what biological material they allow in, because it can contain pests that can damage our goods, our livelihoods, our health and our biodiversity.

"Currently in the UK, we have a laissez-faire attitude - there is an open licence for people to bring in dangerous pests."

But a spokesperson for the Department for Environment, Food and Rural Affairs (Defra) said that a new strategy was in place to "tackle the threat to the UK's native biodiversity from unwanted pest species which have 'hitchhiked' into the UK on plants".

All this week, BBC News will be taking a closer look at some of the alien invaders that are in the UK.

Aggressive arachnid

John Partridge from the British Arachnological Society said his organisation had had an increase in the number of enquiries about "strange spiders".

He added: "We are certainly getting more spiders coming into the UK - and it seems that more are spreading around the country once they are in."

One new inhabitant is Steatoda paykulliana, a false widow spider that is native to Southern Europe, West Asia and North Africa.

It is about 0.7-1.5cm (0.3-0.6in) in size and can bite.

While this spider had been spotted in the UK in the past, it was thought that no colonies had established.

But Stuart Hine, who runs the Insect Identification Service at the Natural History Museum, said this was no longer the case.

He said: "Now we have found it in Plymouth. And it looks as if it is here to stay."

The arrival of exotic spiders and insects that had hitched a ride on various imports was not a new phenomenon, said Mr Hine.

"If there was a warm period they would be able to survive, but a cold snap would kill them off," he explained.

"But now, our increasingly warm climate is starting to suit many more spiders - and once they come in, they are able to stay put."

This has also meant that some invasive species that once only existed within a few small pockets in the UK have been able to spread.

Steatoda nobilis is one such spider.
