Water Spiders (large black) under docks

[Newbiesaukee]

They are probably fishing or dock spiders rather than wolf spiders. Wolf spiders are usually not around water. Both can bite, but rarely bite humans. Neither is "toxic" but any insect or spider bite can cause reactions in some individuals.

But they are very scary looking.

"Fortunately, they have little interest in people. Dock spiders are generally not aggressive regarding humans and will usually hide when we approach. A dock spider will only bite a person in the rare situation that the spider feels threatened, for instance if the female spider is protecting its young.

Unless you grab the spider or inadvertently step on it, you will likely never be bitten."

Certainly putting your foot into a shoe where one is hiding would qualify as "inadvertently stepping on it"

They bite, it hurts, but I have never gotten sick from one, although I've only been bitten by smaller ones. The little buggers crawl to the boat on dock lines and hide under the boat cover. Sometimes when I remove the boat cover I accidently grab one then wham, you know when they bite. Other than that they don't bother you, I leave them alone. If one is where I don't want it, I give it a quick flick into the water, they don't like that, fish think they are tasty. They scramble, on the water to the nearest safe place.

There not wolf spiders, Wolf spiders are all over the place. I don't know the Latin name, But I've never heard anything other than dock spider, they can be about 10 x the size of wolf spiders. In NH anyway.

Scientists have developed inter-species genes to cross the "species line". They have made trans-Mammalian creatures that share strong physical characteristics with Arachnids. Venom has been compromised in the process, in favor of alerting their owners to trespassers.

LOL-hilarious—yet terrifying—at the same time:

Could this be the terrifying wolf spider??

Yes, they can grow to enormous size. They are the unintended consequences of "Science Gone Wrong" at the underwater testing laboratory near Diamond Island performed by the US Navy after world war II. (See Image) First spotted around the lake in 1955

Yes Clint Eastwood,


May not be considered a responsible way to deter them by some folks but seems to be effective. Very common in the desert southwest along with the "50 Foot Woman", and the "Colossal Man"

@Merrymeeting thanks for the informative link.

Next to the dock today, something big and black caught my eye—and disappeared. It had scuttled around the far side of a Hemlock "bush". One of a pair of Eastern Hemlock trees that we keep closely-cropped).

Looking under the freshly abandoned 5-inch circular mesh of spider web, I could see about 200 BB-sized spiderlings.

A couple of years ago, I had seen something similar in the other Hemlock bush and back then, I put my face closer, when the bush started to tremble.

"Momma" Dock Spider had come out to accost the villain who had disturbed her nest—a scary sight, indeed!

I bring this up because I haven't seen any other trees with those Dock Spider webs. (I prefer White Pine trees for New Hampshire homes, but loggers do, too).

Maybe it's time to remove those two "trees" and replant with hophornbeam?

BTW: The video I'd previously placed was marked indicating it wasn't for casual viewing. (And even after several viewings a year apart, I still got goosebumps!) So consider yourselves post-warned.

Perhaps the Arizona Wolf Spider, but it shares no kinship with the Florida Wolf Spider.



(This particular specimen had lost a leg to a Rottweiler).

When I was a kid of about 8, I used to play in a local river in Barnstead, I had one of these arachnids run up my leg into my shorts. It came out due to an immediate (although embarrassing public) disrobing. It is something that crosses my mind to this day every time I am on the water. I will admit that more than a few Water Spiders have met with my wrath over the years since that day.

Wish I had taken a picture...

Just a week or so ago, dock the boat in the evening, next day around 2pm I go to cast off and HOLY CRAP!

Big mama dock spider just overnight had climbed up one of my fenders and made a nest and has hundreds of little babies all webbed at the end of the rope tied up at the cleet!

Now I'm a big guy and they usually don't bother me, but I had to go get a dockhand. "Hey, do you have some big leather work gloves?" I asked, he said no worries I can get that for you,,, then when he saw it, he made the face like the USPS guy in the commercial when he saw the clown. Oh yeah, that's gotta go...
