High temperatures have sparked a sexual frenzy among spiders in Greece - causing the creatures to build a vast network of webs across a lagoon.
The area has been identified as the town of Aitoliko in western Greece by media reports, with the phenomenon attributed to mating spiders.
Footage taken by local Giannis Giannakopoulos shows the web completely cloaking trees, bushes and shrubberies near a lagoon.
The phenomenon is rare, although the webs have appeared before in other parts of the country.
Maria Chatzaki, an arachnologist, said that they're always from the same type of spider in the Tetragnatha genus.

After running the Model 3 through its battery of tests, the NHTSA awarded the 2018 model a five-star safety rating. The Tesla Model 3 gets crash tested by the National Highway Traffic Safety Administration.
'They mate, they reproduce and provide a whole new generation'.
Chatzaki noted that it was a seasonal phenomenon that occurred mainly at the end of the summer and early autumn and arose from a "population explosion". They are not a threat because they are not poisonous and are, in fact, helpful for local communities because they eat mosquitos.
Greek biologist Fotis Pergantis said the spiders are trying to catch gnats. This year, a sizable increase in the mosquito population is also an important driver for the spiders' prolific web spinning.
Neither the gnats nor these spiders are unsafe to humans.
Sadly, the eight-legged architects will soon die off, leaving the web to degrade naturally.
However, Daily Hellas revealed that the rather eerie scene is a yearly sight for the residents of Aitoliko.
