Mike Merchant, Texas A&M AgriLife Extension Service urban entomologist in Dallas, reported that people were exposed to a rather frightening and intimidating scenery, as giant spider-webs could be seen “draping” the trees everywhere. The eerie display was observed by people traveling down CA Roan Drive, in Rowlett, Texas.
CA Roan Drive is a quiet road, traversing Lakeside Park South in the Dallas suburb of Rowlett, says Merchant. He continues by stating that spiders have monopolized the area, with their abnormally large webs, near Lake Ray Hubbard.
The extensive webbing covering the trees seems almost surreal, like dragged out of a gothic story. Thousands of ungracefully tall and thin spiders can be seen moving at fast pace in the webs extending to almost 40 feet high up in the trees and stretching to the size of a football field.
The entomologist continued by affirming that this is a rare, and once-in-a-while unique event. Moreover, the press reported back in 2007 about a huge spider-web discovered at Lake Tawakoni State Park, about 35 miles from Rowlett.
As creepy as it seemed at the time, that particular web spotted in 2007 functioned as a revelation to spider experts (arachnologists). They were taken by surprise as spiders do not usually work together in building their nests, so, this was a sort of cooperation tactic unseen before.
The spiders that developed the webs in 2007 were identified as Tetragnatha guatemalensis.
The spiders of the family Tetragnathidae are known to be non-aggressive to their peers, on the same web. Also, they do not bite humans or pose any threats. When they find the proper conditions, these spiders “join hands” and start creating nests.
But the current event in Dallas is quite the rare sight. The proper conditions that lead to such an occurrence include the appearance of a satiated amount of insects such as midges (small flies that do not bite), which emerge at night in lake areas. Thus, the flies become the spiders’ source of food, as the nests wouldn’t be constructed without proper nourishment.
One should not fear this species of spiders, as they are not aggressive. Amazement might be a more appropriate reaction towards these tiny “architects”. Human intervention via insecticides or other forms of treatment is unnecessary, because the spider-webs are an awe-inspiring sight, casting aside its spookiness. Many scientists and arachnologists consider these webs to be true works of art.
So it seems – spiders have a lot of tricks up their sleeves.
