Dear Kirsten,
This is not a Grass Spider.  This pretty little lady is a Nursery Web Spider,
Pisaurina mira, and she is carrying her egg sac.  Nursery Web Spiders are harmless, and not aggressive except when defending their young.  The female Nursery Web Spider has very strong maternal instincts, and she carries her egg sac with her until she finds an appropriate place to leave it.  She then spins a nursery web and continues to guard the eggs and the young until they are ready to disperse.  Nursery Web Spiders are hunting spiders that do not build a web to snare prey.  The sole purpose of the web is for a nursery.

Hi Daniel!
Thank you so much for this information … Glad to know she is not aggressive despite her intimidating size. I did not kill her, but did gently relocate her with a garden rake( I really needed the length as I fear spiders) ,and she held on to her egg sac , into some woods behind my house. Hope she can find a nice place away from my chair lounger!
Thanks!
Kirsten

I found this gorgeous spider in an out building about a week ago (April 2015). At first I assumed it was some type of Wolf Spider, but further research has me now believing that it might be a Fishing Spider instead. It was rather large in size and was patient enough to allow me to get a few quick photos before it raced off to find cover. I’m also assuming it’s a female. I’m a huge bug fan and love your website! Thanks for what you do!

Dear Bug Geek,
We love your images of a Fishing Spider in the genus
Dolomedes.  Many years ago, Daniel had a photography exhibit at the college in Shepherdstown.

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.

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.

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.
