How many spiders would you consider to be a lot? For many of you, it might be just one. For the rest of us, there’s no arguing that 107 million spiders, is more than a lot! It’s a butt-load.

A huge communal spider web, that stretched over four acres, was recently reported by Wired.com, inside a water treatment plant in Baltimore. This megaweb, housed some 107 Million spiders. It was estimated that almost 95% of the treatment plant was covered by this megaweb; something that shocked even scientists.

“We were unprepared for the sheer scale of the spider population and the extraordinary masses of both three dimensional and sheet-like webbing that blanketed much of the facility’s cavernous interior. Far greater in magnitude than any previously recorded aggregation of orb-weavers, the visual impact of the spectacle was nothing less than astonishing.

In places where the plant workers had swept aside the webbing to access equipment, the silk lay piled on the floor in rope-like clumps as thick as a fire hose.”

Wow! You know that this is quite the impressive spider web, if even tenured scientists were shocked at the sheer magnitude and grandeur of it!!



These megawebs have been reported before here in the U.S., all of which have occurred near water. These massive webs are cast to catch the large quantities of flies and midges that hatch and live near water.

With these megawebs, I found it interesting that they are typically made my multiple species of spider, that co-habitate together for the purpose of catching the massive quantities of flying insects.

Two of the species of spider that are responsible for creating these megaweb masterpieces include the longjawed orb-weaver, and the bridge spider or gray cross spider (also a species of orb-weaver).
