Got Arachnophobia? Giant Spider Web Engulfs Lake Tawakoni State Park in Texas

Web6j00

Not a nightmare but right here, right now, in broad daylight.

Long story short: A vast web crawling with millions of spiders and untold numbers of dead and dying insects entwined in its silk (above) now covers several acres of the park, thick enough in places to block out the sun.

Here's Gretel C. Kovach's article from today's New York Times.

    Got Arachnophobia? Here’s Your Worst Nightmare

    Most spiders are solitary creatures. So the discovery of a vast web crawling with millions of spiders that is spreading across several acres of a North Texas park is causing a stir among scientists, and park visitors.

    Sheets of web have encased several mature oak trees and are thick enough in places to block out the sun along a nature trail at Lake Tawakoni State Park, near this town about 50 miles east of Dallas.

    The gossamer strands, slowly overtaking a lakefront peninsula, emit a fetid odor, perhaps from the dead insects entwined in the silk. The web whines with the sound of countless mosquitoes and flies trapped in its folds.

    Allen Dean, a spider expert at Texas A&M University, has seen a lot of webs, but even he described this one as “rather spooky, kind of like Halloween.”

    Mr. Dean and several other scientists said they had never seen a web of this size outside of the tropics, where the relatively few species of “social” spiders that build communal webs are most active.

    Norman Horner, emeritus professor of biology at Midwestern State University in Wichita Falls, Tex., was one of a number of spider experts to whom a Texas Parks and Wildlife Department biologist sent online photos of the web. “It is amazing, absolutely amazing,” said Dr. Horner, who at first thought it an e-mail hoax.

    The web may be a combined effort of social cobweb spiders. But their large communal webs generally take years to build, experts say, and this web was formed in just a few months.

    Or it could be a striking example of what is known as ballooning, in which lightweight spiders throw out silk filaments to ride the air currents. Five years ago, in just that way, a mass dispersal of millions of tiny spiders covered 60 acres of clover field in British Columbia with thick webbing.

    Mike Quinn, the state biologist who distributed the online photos, and who runs a Web site about Texas invertebrates, plans to drive to the park from Central Texas on Friday in an effort to get some answers by collecting samples.

    Record-breaking rains that flooded Texas earlier this summer inspired outbreaks of crickets and “webworms,” the caterpillar larvae of the white moth. Mr. Quinn said the rains might have something to do with the web, too.

    “You’d have to get a lot of spiders together and feed them a whole lot of food to make a web that big,” he said.

    Whatever caused the vast web, the sight of it has inspired both awe and revulsion.

    “It’s beautiful,” said the park’s superintendent, Donna Garde.

    Freddie Gowin disagrees. It was Mr. Gowin, a maintenance worker at the park, who discovered the web this month when, taking advantage of some of the first dry weather, he mowed the area around the nature trail.

    “I don’t think there’s anything pretty about it,” he said, though “it’s certainly unusual.”

    When Mr. Gowin drives the power mower through the area, webbing wraps across his bare face, causing him to slap at spiders, real or imagined, crawling on his skin.

    The park’s staff says that while the web has killed some leaves, it should not hurt the trees.

    The spiders are “spreading out for sure,” Mr. Gowin said, pointing out cedars that appeared to have a dusting of snow. “They’re going to take over this whole point.”

    The staff expects the web to last until colder weather this fall, when the spiders begin dying off.

    For now the concern is to defend this marvel from teenagers who might take a stick and knock it all down, or little boys wanting to push their little sisters into it.

    “We’ll try to protect it, with what little staff we have,” said Ms. Garde, the superintendent. “I’ll use the web-of-life analogy. If you break one part of the web, it affects us all.”

200 yards of web is an amazing feat by creatures who normally don't work together, like ants. BTW Belinda, you will find spiderman about 80 yards in, on the left. He came out for training and was engulfed.

OMG! what a freakishly large web... where is spiderman when you need him?

In my opinion, this is absolutely amazing. I only wish that I were there to witness it for my own eyes.

I have looked through the internet at a few different species of spiders that have this same characteristic and it's just amazing that these tiny little creatures can work together this way.

The web is just immense looking and to know that it spreads among many acres is just mind blowing! I am no professional and I do not have any theory on this. I just see this as simply beautiful!
