An army of creative caterpillars has covered the entire roundabout in a thick carpet of silk webbing, blanketing plants and shrubs.
The ermine moth caterpillars, possibly helped by countless spiders, have covered almost all of the huge roundabout in the middle of an industrial estate in Croydon, south London.
National Trust wildlife expert Matthew Oates said: "It's amazing - it's contemporary art and it's by moths rather than us.
"It's a protective webbing of silk they spin to protect themselves from predators and parasites.
"They can strip the leaves of whole bushes and small trees but the following year the majority recover if they are healthy.
"It is inspirational stuff."
The huge web is even more impressive because it was made by tiny creatures – each caterpillar measuring less than a centimetre.
Dad-of-two Jaco Zietsman this week photographed the stunning site, which will be used by the caterpillars until they are ready to fly off as moths.
The 38-year-old construction manager from Berkshire said: "At first I thought, I would hate to be eaten by the spider that spun that giant cobweb.
"However, a quick Google revealed it is the work of ermine moth caterpillars.
"You can actually see the caterpillars in there."
Thankfully, the moths and spiders inhabiting the bushes are of absolutely no danger to human life, which will be good news for the residents of Croydon.
