Hi there! This guy was trying to rent a room from us (in South Caribbean of Costa Rica). We successfully removed him from our front door, but curious what kind he was?

Probably Nursery Web Spider

We believe this is a Nursery Web Spider in the family Pisauridae, possibly one of the Fishing Spiders, but its markings are unusual.

This guy jumped off of a book shelf at me today while I was dusting.  It is easily the size of a silver dollar.  Safely released back into the wild. Can you identify it please?

Nursery Web Spider

Dear Zelda,
Your magnificent spider is a Nursery Web Spider,
Pisaurina mira.  We are tagging this posting with the Bug Humanitarian Award, though we suspect your home was cozier than the outdoors at this time of year.  We are not certain if Nursery Web Spiders overwinter, but we suspect they do.  Animal Diversity Web has a nice page on this species where it states:  “Mating occurs in mid-June to mid-July. When a female is ready to lay her eggs, she uses her cheliceres and maxillipeds (grasping mouthparts) to transfer eggs into a cocoon under her abdomen. She carries this sac underneath her body with her fangs (cheliceres) until hatching time approaches. The female then builds another cocoon where she feels it will be safe for the spiderlings. She lashes surrounding leaves together forming a kind of ‘nursery web’ for which the species is named. The female stays there, watching over her brood of pulli (first stage larvae), until they have completed their first larval molt.”

Dear Tony,
Was the cave near a stream or other body of water?  This is a Fishing Spider in the genus

Found her on my curtains last night before going to bed. Wondering if this beautiful spider was a dark fishing spider?

Whitebanded Fishing Spider

Dear Melissa,
We need to begin by telling you we are really impressed that you found this large spider in your home and you were still able to go to bed.  We are also impressed that you agree it is beautiful.  In our opinion, this is a Whitebanded Fishing Spider,
Dolomedes albineus, which is pictured on BugGuide.  According to BugGuide:  “Generally an ID can be made by the white band along the ‘face’ (clypeus).”

Just curious if this is a huntsman spider
Signature: Spider Identification

Fishing Spider, we believe

Your image detail is not ideal for exact species identification, but we are certain that this is NOT a Huntsman Spider.  We believe it is a Fishing Spider in the genus Dolomedes, but we would not rule out that it might be a Wolf Spider like this Thin-Legged Wolf Spider pictured on BugGuide.

Saw this in my backyard today. Located in southern Ontario, Canada.

Fishing Spider

Dear Chris,
This is a harmless Fishing Spider in the genus
Dolomedes, probably a Dolomedes tenebrosus, and BugGuide lists the habitat as:  “Bushes, rocks, etc., near permanent bodies of water, sometimes in dry woodlands.”  Fishing Spiders are capable of walking on the surface of water and they can also dive beneath the surface to escape predators or to capture prey, including small fish.  Fishing Spiders are also called Dock Spiders because they are often found on docks near water.

That is fantastic information. Thanks for the reply. Btw, I never harmed it. Let it do its business. I have seen them in the yard before and wondered what they were. This makes sense as we have a pond in our yard and woods at the back of our property so the habitat description perfectly matches our neighbourhood.
