Heavy rain and subsequent flooding in Victoria has resulted in a “spider apocalypse”.
Thick blankets of spiderwebs across the Gippsland region have been captured in chilling photos shared online.
The photographs were posted to Reddit with the caption “if the floods weren’t enough, I give you, spider apocalypse”.
The East Gippsland region was hard hit in last week’s floods, which resulted in thousands of Victorians being evacuated from their homes.
Like humans, it appears the spiders have sought higher, dryer ground.
What’s occurring is known as ballooning, where cooler weather conditions have resulted in spiders covering stretches of land in cloudlike cobwebs in an attempt to shelter themselves from wet conditions on the ground.
It’s a temporary survival tactic that allows the creatures to continue to hunt while the ground dries out.
With more rain forecast for the end of this week, there’s a chance the arachnids will continue to make their presence known.
Another 50mm of rain could fall in East Gippsland this week.
In an arachnophobe’s worst nightmare, swarms of spiders spin webs in a bush in flood-ravaged Wagga Wagga (map), Australia, Tuesday.
After a week of record rain, floodwaters across eastern Australia have forced the ground-dwelling spiders—and at least 13,000 people—to flee their homes, according to Reuters.
The rampant webs blanketing vast stretches of Wagga Wagga are likely “a dispersal mechanism that allows [spiders] to move out of places where they’d surely be drowned,” said Robert Matthews, a professor emeritus of entomology at the University of Georgia.
Producing large quantities of silk creates a sort of “vast trampoline” that supports the spiders as they’re fleeing the water, he noted.
Matthews added he he has never seen such a “striking phenomenon.”
“Gee, it’s impressive.”

Spiders spin thick webs as floods force them to move to higher ground in Wagga Wagga, Australia, on Tuesday.
The wet year may have has led to a boom in insects in this region of Australia—an abundant food source that’s also likely inflated spider numbers, Matthews said.

There may be hope in sight yet for human and beast alike. The Murrumbidgee River—source of most of the flooding in Wagga Wagga—is slowly receding after reaching 34 feet (11 meters) on March 6, according to Reuters.

Spiderwebs blanketing fields on March 6 “almost look like snow—it’s so amazing,” Matthews said.
The webs appear to be the work of sheet-web spiders and wolf spiders, two species not considered dangerous to people. It’s late fall in Australia, when spiders are at their biggest and most plentiful following the bountiful summer, he said.
Overall, the pictures illustrate “the versatility of things [spiders] can do with silk,” Matthews said.
Silk “has been a huge evolutionary breakthrough,” he said, and “this is one more example of why spiders have been a successful group.”

Some Wagga Wagga residents have found the spiderwebs (pictured on March 7) a pleasant distraction after days of battling floods. “I have never seen spiderwebs like it,” resident Janet Hume told the Telegraph.

Spiderwebs billow in the wind in Wagga Wagga, Australia, on March 6. Now battling floods, eastern Australia only recently emerged from a decade-long drought and its worst bush fires in history.
