Happy Halloween: Giant Spiderweb!
You might remember my coverage of the giant spiderweb that ate Texas in 2007. For Halloween 2010 I am happy to report for your creeping-out pleasure that a new giant spiderweb was reported in Maryland!
An Immense Concentration of Orb-Weaving Spiders With Communal Webbing in a Man-Made Structural Habitat (Arachnida: Araneae: Tetragnathidae, Araneidae). American Entomologist 2010: 56 (3), 146-156
The giant web was inside a waste water treatment plant, an open building covering almost 4 square acres. And “immense†doesn’t really begin to cover it. From the paper:
“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 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.â€
Remember, that paragraph was written by 5 mid-career professional entomologists and arachnologists. If they were a bit freaked out by the size of the web….Well, you can draw your own conclusions.
One of the amazing bits of info in this paper was a quantification of just how much of this facility was filled with web. As you can see from this data table, in several areas over 95% of the space was filled with spider webbing. The webbing was so dense that it actually pulled some of the 8-foot long fluorescent light fixtures out of place! The authors also measured the number of individual spiders per cubic meter–and got up to 35, 176 spiders/m³ in some areas.
Oh, and the they describe their estimates of total web volume as “markedly conservative†and “representing a minimum volume†(emphasis mine). OMFG, indeed!
The researchers also mention the giant Texas spiderweb in their discussion, and suggest that giant multi-species webs may be more common than we realize. Yay!
BTW, one of the authors on this paper also authored a recent paper on gigantism in spiders. I mention that mostly to have an excuse to link to Kingdom of the Spiders. William Shatner + Giant Spiders = Epically Bad Movie WIN!
(also, am I the only one that thinks that torch placement is….unfortunately suggestive?)

AHHHHHHHHHHHHHHHHHH. Oh and one more thing, AHHHHHHHHHHHHHHHHHH!
Yea…I’m gonna go ahead and add this to the list of things I never ever want to ever see. Ever.
I shared this with my friend. He did his whole bathroom in spider motif for the Halloween party, but it had nothing on this.
Okay, I like arachnids and even I think this is a bit distressing.
You wonder what so many spiders would find to eat. Wait,… did they count the entomologists afterward?
Did they collect the spider webs and spin them into yarn and then make the yarn into bullet proof clothing?
@davew: “You wonder what so many spiders would find to eat. Wait,… did they count the entomologists afterward?”

How were that many spiders getting food? I would think a web like that would have killed off the insect population long before it got that big.
@davew: @devianttouch: I’m pretty sure these spiders have evolved to feed off fear.
It was a “waste treatment plant”.
You have heard the joke, what weighs 5 tons, has four wheels and flies? A garbage truck.
The is Maryland. I suspect it is part of Christine O’Donnell’s plan for health care. A natural treatment for anyone who swallows a fly.

Wow – a really inter…*inarticulate gagging sounds of horror*..esting post…
Am I wrong to like this?
spiny orb weavers = effen cool looking
boo!
I’ve posted this before, but my niece (than 6) was rumored to have once kissed a spider. I asked her about it, mostly to tease her, and she replied “But it was soooo cute!”
@daedalus2u: O’Donnell is Delaware, not Maryland.
And as a Baltimore City resident, I’d really like to know where exactly this web is located, as I can’t find any specifics anywhere as to the town we’re talking about. If I’m going to freak out, I’d like to aim it properly/
Has Jen McCreight seen this yet? Somehow she managed to move to the one place in America where spiders rule.
We treat them like our little bug eating pets.
