Hi, I found this spider outside while I was stacking wood. It’s pretty big, about the size of a silver dollar or bigger. I was wondering what it was and if it was venomous.
Thanks!

Dear Marissa,
You encountered a Fishing Spider in the genus
Dolomedes.  They have venom, but they are not considered dangerous to humans.  Fishing Spiders are generally found not far from water.

Six Spotted Fishing Spider

Six Spotted Fishing Spider

Dear bug man,
Your image is gorgeous.  This is a Six Spotted Fishing Spider,
Dolomedes triton.  Though the entire genus is commonly referred to as Fishing Spiders, the Six Spotted Fishing Spider is one of the species most closely associated with water.  As you image documents, the spiders are able to disperse their weight across all eight legs and then walk on water.  Fishing Spiders can also dive beneath the surface of the water to hide from predators and they occasionally catch small fish, tadpoles and other aquatic creatures.

I found this spider in my fireplace about 3 inches from my face while fixing the fireplace in August, northern New Jersey. I released it shortly after this photo session.

Fishing Spider with Egg Sac

Fishing Spider with Egg Sac

Hi Tom,
You have correctly identified a Fishing Spider in the genus Dolomedes, but we are uncertain of the species, though if you are located far from water, this is most likely
Dolomedes tenebrosus.  This is a female and she is carrying an egg sac.  Female Fishing Spiders carry an egg sac around until they find a suitable location to spin a nursery web in which to deposit the egg sac.  The female continues to guard the egg sac in the nursery web until she dies or until the egg sac hatches and the spiderlings disperse.  Because of your kindness to this expectant mother Fishing Spider, we are tagging this posting with the Bug Humanitarian Award.

This guy or gal was spotted on the sand at a beach in the northern lower peninsula of Michigan today. An hour of digging around got me nowhere. But given its size (that’s a standard sized bic lighter) and what few markings I can make out, I want to go with a wolf or jumping spider of some sort but I’ve seen nothing that matches it or its camouflage ability. Can you ID this one?

Dear Faith up North,
This is a Fishing Spider in the genus
Dolomedes, but even though we cropped to the spider and adjusted the contrast to provide more detail, we cannot be certain of the exact species.  Please refer to BugGuide for possibilities.  We do know that surroundings can have a pronounced effect upon which individuals in a particular species are able to survive and pass on genes, and it is very plausible that this light colored Fishing Spider may be uncharacteristically colored when one considers typical members of the species.  Because it is so well camouflaged, it as well as its ancestors and its progeny may be better suited to survival in this particular habitat.

Thank you. I’m leaning toward D. scriptus.

Thank you!
No one identified my spider from a couple months ago?
Attached.
Notice her front 2 leggies are together, so dainty.
I wondered at first, as you might well imagine.
She was larger than your usual Vt spider…
Best!

Dear MG,
This is a Nursery Web Spider,

Taken at Balsam Lake Provincial Park, Ontario…I dislike spiders but found this one intriguing, he/she was on my tent, didn’t like the light when shined on him…can you identify…pretty fast mover when placed on tree after removal from tent…camp site was not near water, lake was about a mile away…at least 2-2 1/2 inches in total diameter…he seemed to like hanging out on the mesh of my tent…thanks in advance, I have never seen such a large spider in Ontario…almost tarantula like in appearance, hairy, brownish/blackish…

Hi Kim,
Even though you indicate that the lake was some distance away, this is nonetheless a Fishing Spider or Dock Spider in the genus
Dolomedes, and they are generally found in close proximity to water.
