Chinese locale ID please, and Hello everyone.

[venwu225]

Happy new years everyone:

I am new to the forum and have a animal from Beijing China, found locally in
the Ping Gou area.

I wasn't able to get a photo of the spider's web in its natural environment,
but it was essentially found in cervices where it lays a double layered web,
and awaits for passing prey. The web is littered with debris of death prey,
which ranges from beetles to pill bugs. They are fairly common around beijing.
I made a poor attempt at drawing the most frequently seen webbing. As you
can see from the photo.

Any ideas on the ID?

So far I am providing it with a enclosure with sufficient moisture and
ample vertical surfaces, as I found this particular animal under a cavity
of a tree bark.

I don't think I've ever seen anything like that. Weird! Any chance you could get a shot of the eyes?

hehe, i like the drawing, that's pretty sweet sorry i can't help with an ID though... :8o

 

[venwu225]

no one knows? thats pretty amazing considering how common it is locally in beijing. And boo on me for not knowing. But then again, it is pretty esoteric information...

Awesome! Family Oecobiidae. Uroctea. Two known species in China, U. lesserti recorded from Beijing.

you are awesome...

Any literature/peer reviewed journals on their care and behavior?

 

[venwu225]

Web construction complete. I think the animal just has to gradually thicken the webbing. It looks pretty much like the ones in nature but just thinner. I collected it from very dry areas, so the only source of moisture in the well ventilated container is piece of folded paper towel about 8 times the "volume" of the spider. I will wait for a day or two before I attempt feeding, and I will keep everyone posted.

Thanks for looking.

It's a species of Urocteidae. Compare against the picture of U.durandi at:

http://en.wikipedia.org/wiki/Uroctea_durandi


According to the Golden Guide "Spiders and their Kin," there are a dozen species scattered around the Old World. They live under stones and in rock crevices,"where they make a dense, flat silk tube up tp 5cm ( 2") wide or a series of sheets above and below the spider." They are harmless also.

Hi.
Family Oecobiidae. Uroctea. Two known species in China with U. lesserti recorded from Beijing. The other is compactilis.
Durandi is Mediterranean.
Urocteidae is not a valid family.

Any literature/peer reviewed journals on their care and behavior?

Hi.
I'm not sure if there is anything on their care and behavior.
The closely related Oecobius in my area prey primarily on ants.

hi


in Mediterranean there is a beautiful Uroctea durandi.

The spider above is an Oecobiidae - Uroctea sp.
