If only they were clever Halloween decorations.
The San Francisco Bay area has received numerous shocking reports and photographs of spiders falling from the sky and sticking to surfaces when they come ashore.
Residents have noticed pieces of white cobwebs containing baby spiders that apparently need a new place to live during the “inflation” process, the San Francisco Chronicle reported.
“What they are are strands of silk that baby spiders use to disperse,” Fred Larabee, an assistant professor of biology at San Jose State University, told the newspaper, comparing nature’s spooky act to dandelion petals. waving in the wind. .
“To get away from where they were originally born, they spin these silk threads and they get caught by the wind, which attracts the spiders to a new place to live, to new habitats, so they don’t compete with their siblings,” he explained.

According to Larabee, membrane clots arise, as residents see them, when individual threads become intertwined.
One Pacific Grove resident, Brook Shadwell, described seeing cobwebs “everywhere” on his nabe, including on the ground, stuck to bushes, on power lines and almost everywhere, even, alarmingly, on his own hand .
“They look almost like the fake spider webs you buy at the Halloween store,” Shadwell said, adding that as a lifelong resident of the area, he had never seen these spooky aerial phenomena before.

“It was very silky and sticky,” he said, calling the phenomenon “very strange.”
Larabee said this fall appears to be a particularly booming cycle of spider births.
“It’s a great opportunity to learn more about spiders,” Larabee said. “It gives the public a chance to see some really interesting biology that they might not see otherwise.”
And who doesn’t mind suffering another scare in time for Halloween?
