A spider web 300 meters long was woven in Greece, with probably thousands of arachnids underneath – National

Visitors to the city of Aitoliko, in western Greece, can be forgiven for feeling like Tolkien's J.R.R. Frodo Baggins, after discovering Shelob's hideout in the second half of The Lord of the Rings.

They do not have to fear as he did – yes, spiders have woven a 300-meter strip along the coastline, and there are thousands under it.

But according to a professor, these spiders do not threaten humans.

Tetragnatha spiders are known to build large canvases in order to mate, reported BBC News.

Nevertheless, according to CNN, at least one resident of the region has never seen them as big.

"It is natural for this area to have insects, nobody is particularly worried," Giannis Giannakopoulos told the network.

"But I have never seen such large spider webs in my life."

Molecular biology professor Maria Chatzaki told the Greek Newsit.gr website that the increase in temperatures, food and humidity had favored the conditions for spiders to have many children.

As translated by the BBC, she said, "It's like spiders are taking advantage of these conditions and organizing a sort of party.

"They mate, they breed and provide a whole new generation."

Chatzaki does not expect spiders to interfere with plant life.

"The spiders will have their party and will die soon," she said.

Giannakopoulos captured a video showing the canvases along the Aikolito coast.

Weather conditions in Aikolito have also allowed midges to flourish – and they are the favorite food of Tetragnatha spiders, CNN Fotis Pergantis, a biologist and president of the Messolonghi Lagoon National Park, told CNN.

As the mosquitoes multiplied, they caught the attention of spiders.

"It's the simple prey-predator phenomenon," said Pergantis.
