Your letter to the bugman:  Hello Bug Folks!
I’ve got some wonderful photos of a Dolomedes tenebrosus (Fishing Spider) we caught last night in our Ohio basement. My housemate deals in exotics and this little friend was feasting on escaped crickets, good spider!
It’s actually bigger than some of his tarantulas. Housemate decided to keep it, at least for now.
I thought of you guys immediately, knew you’d want to see the photos (Sharpie marker for scale). I don’t know how dimorphic they are but can you tell if it’s a male or a female? I don’t want to keep calling our guest “it” and “spider,” I feel anybody living with us should have a name. The spider doesn’t care, but I do.
Thanks!

Fishing Spider

Dear KLeigh,
Please use our standard submission form for future submissions.  Our gut instinct is that this is a female Fishing Spider.  Many Spiders can be sexed because males have much more pronounced pedipalps that are used for mating and females are usually larger.  We will attempt to do some further research on telling male and female Fishing Spiders from one another.  Perhaps you will enjoy these images of mating Fishing Spiders from our archives.

Your letter to the bugman:  I was watering the plants in my garden and saw a bizarre pattern on my apple tree.  As I got closer I couldn’t decide if it was part of the tree or if it was a really well camouflaged bug.  I had to get really close to see that it was a spider!  I have never seen anything like it.  It was perfectly blended into the bark of the tree.  What is this amazing spider?

Probably White Banded Fishing Spider

Dear Curious in GA,
This magnificent spider is a Fishing Spider in the genus Dolomedes, and we believe it is a White Banded Fishing Spider because of its resemblance to the individual in this image posted to BugGuide.

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.”
