40 foot long spider webs in Texas happening
“Insecticides or other treatments are really unnecessary as this spider is essentially harmless," Merchant said. "Although the communal nest may look spooky, they too are basically benign and are a sight more to be appreciated than feared."
hmm
Thousands of spiders coming together to weave 40-ft-tall webs in Rowlett, Texas, are 'more to be appreciated than feared.'
Visitors driving along CA Roan Drive, a tree-lined stretch of road in the Dallas suburb, will notice giant “glistening webs ... draping the trees like shrouds," as described by Mike Merchant, a Texas A&M AgriLife Extension Service entomologist in Rowlett.
These webs extend up to 40 feet and are inhabited by the thousands of spiders who came together to spin them in a communal effort.
We are looking at something five times as big as what one would see on a Sci-Fy Hollywood set.
Spiders typically work alone to construct their webs. So finding spiders working together to build a huge web in what was more of a cooperative or ‘communal’ scenario was a real surprise for many experts.
The spiders were ultimately identified as Tetragnatha guatemalensis, a species that had been previously known to build communal nests under certain conditions, but rarely in the United States.
Tetragnatha guatemalensis, dubbed the Guatemalan long-jawed spider, can be found in areas ranging from Canada to Panama. The spider is approximately an inch long and has a red-orange head and thorax.
They take a "more the merrier" attitude with other spiders as well, showing no signs of aggression toward other species sharing their web.
