WILLS POINT, Tex., Aug. 29 — 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.

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.
