Cranberry Bogs Use Spiders Instead Of Pesticides

Hey what are you doing, let’s talk about cranberries! Surely you know, the cranberry is the Official Berry of my wonderful Commonwealth. The tart berry is one of only a few native North American fruits, like the pawpaw. The previous sentence has a lie because cranberries aren’t drupes, and I know that because I just learned what a drupe is. Cranberries are, in fact, epigynous or false berries, something else I just learned about and about which we’re not going to talk about anymore because this post is about making nightmares not destroying dreams, which are in fact two different actions. (Unrelated, North Carolina can’t decide on an official berry and has both an official state red berry and an official state blue berry. (You’ll never guess the official blue berry of NC.))

Massachusetts boasts 30% of global cranberry acreage, which is a lot and also a very nice and real fact. Most cranberry products come from Oceanspray, a farmer owned cooperative with 700 member owners. This is a neat and less capitalistic model than most corporate juice production, which may make Oceanspray products taste a little sweeter. You remember this TikTok which increased sales for both Oceanspray products and Fleetwood Mac.

Cranberries are grown in bogs, but since bogs can’t generally support a large person’s weight, farmers harvest cranberries by flooding the bog and corralling the cranberries together like so many tart reddish sheep. In this analogy, cranberry sauce is the wool of those tart sheep. And below here is where the nightmares start, so consider not advancing if you’re of gentle disposition.

All this was needless preamble to get to what I really want to tell you about which is, according to this lost Tumblr post, if you try to get a job at a cranberry bog you might get asked how you feel about spiders and that’s a weird interview question and you might consider not telling the truth because what you want to do is wake up early and be one with the (false) berry. What you want to do is go back to your boggy roots. What you want to do is farm cranberries like a cranberry farmer. But if you do have a problem with spiders and you don’t say anything it’s going to be another problem, and buddy, it’s gonna to be a big one. You see, cranberry farms have been moving towards more organic farming methods which preclude the use of pesticides and so to keep the insect population down, the farmers encourage wolf spiders to live in the bogs. I’m sorry, I meant WOLF SPIDERS. And when they flood the bogs to harvest the cranberries, the WOLF SPIDERS, who are probably called WOLF SPIDERS because they look like little 8 legged wolves, don’t ask me, I’m not an arachnobiologist, flee the deluge for higher ground, because while they can swim like Michael Phelps, they do not prefer to. So they seek higher ground and guess what the higher ground is, Joann, it’s you. You’re the higher ground.

And so the cranberry farmers will ask you how you feel about spiders before hiring you because you might have dozens of swimming WOLF SPIDERS climbing out of the water up your waders and into your hair, but you’ve got to be fine with it because the WOLF SPIDERS are your fellow cranberry bog employees and everyone, even WOLF SPIDERS deserve a safe work environment. Wear a turtleneck or something. Maybe you’re thinking, it’s fine, WOLF SPIDERS don’t bite, and if they do, they’re not venomous, but they do bite and they are venomous, but maybe it all works out if you let them use you for higher ground.

Playing the SpiderHarp

“SpiderHarp started as a large-scale model of an orb spider’s web, with the aim of uncovering the mystery of how spiders sense … vibrations and how it translates into information the spider uses to localize activity on its web.” A recent Oregon Public Broadcasting story [via mefi] led me to this cool video of the SpiderHarp in action. More SpiderHarp here.

True Facts About the Ogre-Faced Spider

Ze Frank released the most recent video in his True Facts series about animals last month. Meet the ogre-faced spider. Admittedly I haven’t watched any of the other True Facts videos in awhile, but this one seemed unusually informative (while retaining Frank’s signature humorous asides). I would watch an entire nature series like this: funny but not dumbed down on the science side.


Rules

In the email Jason sends to guest editors, one of the rules is, “Don’t embed any videos of ants trying to mate with their queen as their queen gets bit in the head by a spider.” I thought it was an oddly specific rule, but, you know. Today, however, when I came upon a video of ants trying to mate with their queen as their queen gets bit in the head by a spider I felt like maybe you’d want to see it. I’m not going to embed it, because that would be breaking the rules, but here’s the link because science. “A more macabre video from the insect kingdom would be hard to find”.

PS The rule about not posting pictures of your cat is new as of last night.

Spider silk tapestry

The American Museum of Natural History is displaying a 11’x4’ tapestry made completely of spider silk. It took four years, required more than one million spiders, and cost $500,000 to make.

The task of silking a spider starts with a small machine — designed centuries ago when the first attempts to silk spiders were begun — that holds the spider down.

“The spiders are harnessed … held down in a delicate way,” Godley says, “so you need people to do this who are very tactile so the spiders are not harmed. So there’s a chain of about 80 people who go out every morning at four o’clock, collect spiders, we get them in by 10 o’clock. They’re in boxes, they’re numbered, and then as they get silked, about 20 minutes later, they get released back into nature.”

The vivid yellow is the natural color of the spider’s silk. If you can’t make it to see the exhibition at the AMNH, check out a video featuring the tapestry. (thx, renee)


For her Mended Spiderweb project, Nina Katchadourian

For her Mended Spiderweb project, Nina Katchadourian found spiderwebs in need of repair and fixed them with a needle and thread.

All of the patches were made by inserting segments one at a time directly into the web. Sometimes the thread was starched, which made it stiffer and easier to work with. The short threads were held in place by the stickiness of the spider web itself; longer threads were reinforced by dipping the tips into white glue. I fixed the holes in the web until it was fully repaired, or until it could no longer bear the weight of the thread.

The spiders didn’t think much of her handiwork:

The morning after the first patch job, I discovered a pile of red threads lying on the ground below the web. At first I assumed the wind had blown them out; on closer inspection it became clear that the spider had repaired the web to perfect condition using its own methods, throwing the threads out in the process. My repairs were always rejected by the spider and discarded, usually during the course of the night, even in webs which looked abandoned.

Man bitten by a deadly Brazilian Wandering

Man bitten by a deadly Brazilian Wandering Spider is saved by his cameraphone pic he took of the spider. “Experts at Bristol Zoo were able to identify [the spider from the photo] and suggest an antidote.”
