In Greece, the spiders captured the whole beach


Some of the locals attribute the sudden emergence of the spiders to the rise in mosquitoes in the days preceding the phenomenon.

The lagoon in Aitoliko, Western Greece, is now shrouded in webs, burying vegetation in a mass of spider silk, filled with mating spiders and their young.

A vast area of greenery has been covered by the web, reports the Daily Hellas.

Local Giannis Giannakopoulos shared pictures Monday of what he described as a "strange and unprecedented spectacle" on his Facebook page, garnering dozens of shares. It was all spun by arachnids known as "stretch spiders".

"These spiders are not risky for humans, and will not cause any damage", molecular biologist Maria Chatzaki told Greek news websites.

The thick, fuzzy covering comes from Tetragnatha spiders, a type of spider that frequents tropical climates, as Maria Chatzaki, a biology professor at Greece's Democritus University of Thrace, told Newsit.

"The spiders will have their party and will soon die", she said, per the BBC. She explains, "When an animal finds abundant food, high temperatures and sufficient humidity, it has ideal conditions to be able to make large populations".

Underneath these huge webs, Chatzaki says that there are populations of spiders mating, according to Live Science. They frequent regions all over the world, but often stick to habitats near the water.
