Spider webs have cloaked the trees along one of the streets in the Dallas suburb of Rowlett. The amazing spider handiwork has left the Texas folks baffled since it is highly unusual for spiders to work in groups because they are known to normally work alone.

The giant Dallas spider webs were draping the trees in the town's CA Roan Drive. According to Discovery News, the webs reached up to 40 feet into the trees and accommodate thousands of spiders. Texas A&M Agrilife Extension Service urban entomologist Mike Merchant, who discovered the webs, said that the massive web structures are rare but not entirely unprecedented.

"CA Roan Drive is a quiet stretch of road running through Lakeside Park South in the Dallas suburb of Rowlett," Merchant said. "But in the trees along a football field-length stretch of the drive, the spiders have been taking over."

"Someone stepping off the road for a closer look will see thousands of lanky spiders darting among the webs that extend up to 40 feet into the trees," he added. "There is a surreal quality to the extensive webbing covering these trees."

The spiders that are responsible for the giant Dallas spider webs are still unknown. However, AgriLife Today hinted that it might be a spider in the Tetragnathidae family. As per Clapway, the Tetragnatha guatemalensis spider, which builds huge nests and can be found in Minnesota, Kansas, New Mexico, and Southern California in the U.S., is the culprit of the strange phenomenon.

Seeing thousands of spiders working together to create the massive spider Dallas spider webs is indeed strange since spiders often prefer to work alone. But scientists suggested that the webs are strung in collaboration to take advantage of rare invasions of insects, a hatch of midges or other water-borne insects from the nearby lake, Boing Boing noted.

While the giant Dallas spider webs look creepy, it's harmless since the spiders are not aggressive, Latinos Post reported.

Meanwhile, though the giant Dallas spider webs were unusual it's not the first time that communal webs have transpired in Texas. In fact, the last reported incident was found inside Lake Tawakoni State Park in 2007, Science Recorder has learned.
