A colony of huge cave spiders are finally heading home after 10 years.
一群巨大的洞穴蜘蛛在实验室待了10年之后最终被送回家。
Squatting in a house for a decade
The spiders have been squatting in a disused废弃的 building in the Yorkshire Dales after escaping from a nearby cave, hidden in scientists' equipment.
Volunteers and staff from the National Trust's Malham Tarn estate in North Yorkshire are now transporting the spiders back to their natural home.
Measuring seven centimetres across, the cave spiders are amongst the largest spiders found in the UK.
"The time has come for the cave spiders to be relocated back to their natural homes," says Martin Davies, National Trust property manager for the Yorkshire Dales in the UK.
The old house is due to be renovated更新，刷新 for use by visiting schoolchildren and walkers, Mr Davies explains.
Stow away
Ten years ago, a team of archaeologists考古学家 from the University of Bradford carried out a major survey of the nearby Chapel Fell cave.
At the end of each day, they took their equipment to a nearby house to store overnight.
In doing so, they accidently carried with them spiders hiding among the equipment.
From then on, the spiders successfully set up a new colony in the small dark building.
The cave spiders Meta menardi and the related Meta bourneti are rarely seen beyond their natural habitat of caves and tunnels because of their aversion憎恨，嫌恶 to light.
They are active hunters and normally feed on small insects.
Although harmless, they can occasionally bite if provoked激怒.
Homeward bound
The spiders are collected using a contraption奇妙的装置 called a 'pooter昆虫虹吸瓶' which sucks the spider up safely into a container.
The spiders are then put into individual plastic boxes and released back into the darkness of the caves.
More than 150 spiders will make the short journey back to where they belong.
Once back in the caves, the spiders won't be forgotten, Mr Davies says.
"We have plans to use a small outbuilding附属建筑物 as a spider house, with a window on their mysterious world."
