Elkhead, Oregon, along forestry road 500 ft elevation approx , North Douglas County, Oregon, USA
November 1, 2009
Came across this in the rainy autumn hunting grounds of Oregon's logging terrain. I couldnt see the spider if there was one. The sack is about 1 1/2 inches in diameter with a hammock underneath and some other oblong sack-ish formation in the dirt below made of web. It reminds me of tarantulas, the webby mat underneath some hanging orb. ANY IDEAS??????? it's driving me nuts!! I found 2 other hollow-ish stumps with these inside. This is southern oregon, autumn, drenched in rain, just after several days of rain.

Moved from ID Request.

Process of elimination...
If someone can tell that this isn't made by an insect, I think it can be moved to unidentified spider egg sacs.

 
Could you please move this image to unidentified spider egg sacs

Some contestants...
Tegenaria duellica sometimes suspends their sacs like this, and also covers it with debris on occasion... but there's a variety of other spiders that make similar egg sacs. I'm not sure this can be ID'd from this image alone (would need to see the mama).

I don't think there are any tarantulas (family Theraphosidae) in Oregon, but I guess if you're far south enough maybe...(not sure, though)? The only genus possible would be Aphonopelma. And I don't know much about tarantula egg sacs, but I thought they were more like a literal sac and the mother sort of holds on to them, like in the example here? (As opposed to being suspended in the air.) Not at all sure, though. I guess different genera or species might do things differently.

There are other mygalomorphs in Oregon, aside from tarantulas, but most are burrowers so I'm not sure their sacs would look like this.

Oh, and one thing I noticed: 1.5 inches in diameter? Is that a typo? That seems sorta big. And yikes! Creeeepy face!
