Pet Zoropsis - Zoropsis spinimana - female

Pet Zoropsis - Zoropsis spinimana - Female
Cupertino, California, USA
December 21, 2002
Body 0.7"
This is a zoropsis spinimana. Almost no information exists online or in guide books on this species; yet they are very common, and quite striking. Beautiful patterns on the carapace and abdomen.
They appear frequently in my home in South SF bay, CA (Mediteranean climate).
They climb high on the walls, but may also be found near floorboards.
The spin a "cotton-candy" silk tent to protect their egg sacs--extremely sticky stuff. Sometimes they line walls with strands of "wooly" silk, but otherwise do not use a web.
Someone, please give this species a common name! They are native to France, so I would like to know if the French have a common name.

If you still get these
There is a citizen science project if you don't already know:

We still get them
Thanks for the link. I still have one in captivity and will consider sending a specimen to this project.

Many spinimana's have showed up in our house since I posted this 9 years ago! I keep them in captivity (as opposed to releasing them) not only because they are invasive, but have also been found to be mordacious and necrotic. A paper published in France claims their venom may induce symptoms similar to the brown recluse. It certainly looks to me like their fangs can break the skin and I have seen what they do to crickets. I mention this because all of the information I've found online in the U.S. claims they are harmless. I presume that the "harmless" claim stems from the fact that they are non-aggressive.

If not for those concerns they would make perfect pets. They are incredibly clean and easy to care for, alarmingly easy to breed, and exhibit truly interesting behavior.

 
do you have photos of juveniles?
Since you mentioned they are easy to breed, I thought you might know what a juvenile looks like. I captured a spider last night that has similar markings to Z. spinimana, but it's about half the size and not nearly as darkly marked.

I also discovered that I had mistakenly identified an adult Z. spinimana as a wolf spider right around this time last year. We found it at night on the side of our apartment building. This one was inside, on the wall.

I added these photos to the ID Request page. I'm hoping someone can help me with an ID.

The Italians call this "falsa licosa" or false wolf spider. That's the only name I could find.

The spider looks like a cribellate analog of the wolf spiders.

I created a guide page for this.
