This spider was in the same vicinity as one I posted recently (2017/04/13/nursery-web-spider-panama-believe/ ). This one looks like it could be the same species but it has a tiny triangular abdomen.

Nursery Web Spider

Hi again Peter,
This does look like the same species of spider to us, and the smaller abdomen might be due to this particular individual not having fed in some time.  Including the image of the Spider’s face is a big assistance in confirming that both this individual and the previous individual are indeed Nursery Web Spiders, and probably Fishing Spiders in the genus
Dolomedes, because the eye pattern on your Spider matches the genus pattern pictured on BugGuide.

Is this a Giant Crab Spider (Sparassidae)? I found it on rocks in an almost-dry stream bed in Darien, Panama on March 27th (dry season).

Nursery Web Spider, we believe

Dear Peter,
This looks more like a Nursery Web Spider in the family Pisauridae to us.  We will attempt additional research.  Members of the family known as Fishing Spiders are frequently found near water.  Here is a similar looking individual from Honduras on Arachnids My Species.

I have a backyard pool that we don’t clean or put chemicals in during the winter, so by the time spring comes the pool is full of life. After a storm came a trash bag flew into the pool and when I pulled it out it had this guy on it. From his (or her?) distinctive spots I assume it’s a 6 spotted fishing spider, but I’m not sure. The spider would have had its legs hanging a few mm off of a quarter if he had been standing on one. Around the edge of the pool I have been finding dried out dead spiders stuck on the side with a little bit of webbing. Could those be what this guy leaves behind? How big can these spiders get? Thanks!

Six Spotted Fishing Spider

Dear Vikky,
We agree that this is a Six Spotted Fishing Spider,
Dolomedes triton, a species that is generally found near a body of water, and it sounds like your dormant swimming pool has been a perfect environment for her.  Since it sounds like you are getting ready to clean the pool, we hope you are able to relocate this beauty so that she can live out her life and produce progeny.  The “dried out dead spiders” you describe might have been prey, or they might have been cast off exoskeletons left behind when this individual molted.  Since it is the first of the month, we will be selecting your submission as the Bug of the Month for April 2017.

We found this large spider on the front porch eating dinner. Then shortly found what we belive to be the father carrying the eggs on his back. Not sure what it is… if you could please help us identify them that would be cool.

Female Wolf Spider with Spiderlings

Dear Robin,
The second Spider is a female Wolf Spider and she is carrying Spiderlings, not eggs.  Thanks so much for including the penny for scale as it provides a sense of the difference between the sizes of these two spiders.  The Spider with its prey is a much larger individual.  The carapace looks to us to resemble that of a Fishing Spider (see this BugGuide image) in the genus
Dolomedes rather than a Wolf Spider and Fishing Spiders are larger.  Wolf Spiders in the family Lycosidae and Fishing Spiders in the family Pisauridae are both hunting spiders that do not build webs to snare prey.  We may be wrong, bug we believe the larger spider is a Fishing Spider in the genus Dolomedes.  The prey appears to be a Scarab Beetle.

This is a picture I took in Mid fall 2016.
It was taken in SW WISCONSIN USA. Vernon County.
It was found on a house (doorjam leading into house) that is built on the bluffs which surround the banks of the MISSIPPI RIVER.
Please help identify.

Fishing Spider

Dear Angela,
Your Spider is a member of the genus
Dolomedes in the Nursery Web Spider family.  Dolomedes species are commonly called Fishing Spiders or Dock Spiders because they are generally found near bodies of water, and though fish do not constitute their primary source of food, Fishing Spiders are capable of walking on the surface of water and then diving below the surface for protection or to capture aquatic prey, including small fish.

Hi there, I found this spider at the doorway of my local McDonalds and had a leg span of about 20cms tip of back legs to top of front legs. It was also really hairy and a guy walked passed it and petted it like it was a furry little kitten.

Possibly Water Spider

Possibly Nursery Web Spider

There is not much detail in your image, so a definitive identification may be impossible, however, the manner in which your spider holds its legs reminds us of the posture of a Nursery Web Spider or Fishing Spider in the family Pisauridae.  This iSpot image shows that posture.  It may be a member of the genus Nilus which is represented on iSpot.

Hi there Daniel,
Thanks for the response, much obliged…. guess I always hope that what I’ve found was some super rare, over poisonous mutant spider…. but it’s never the case, lol!
