Spider burrow? - Ariadna bicolor

Spider burrow? - Ariadna bicolor
Norfolk, Virginia, USA
February 3, 2008
Found on underside of a piece of tree bark. Hole is 2mm wide. I have the piece of bark in a container to see what lives within, but so far nothing has appeared. If something shows itself, I'll try to get an image of it.

Moved from Tube Web Spiders. According to Spiders of North America, Ariadna bicolor is the only species in the east, except for one that's limited to southern Florida.

Thanks Charley...
Maybe I can find one of these spiders soon!

Can't wait
to see your images when you do find one! You really should be making coffee table books--we're all very lucky to have you sharing so many amazing photos with the world. I can always pick out which ones are yours just from the thumbnails.

I suspect Segestriidae, of which Ariadna bicolor is a common example. This book has some great photos and descriptions of spider webs.

I'm still watching the entrance, but haven't seen anything emerge yet. Maybe it outgrew the burrow and moved to a larger one. There are two of these tubes in this piece of bark and the other one was slightly smaller. I thought I saw something at the entrance of the smaller one, but it has not reappeared.

I sure would like to get an image of one of these spiders.

Thanks for the link too!

Seeing the spiders
I don't know if you've had any luck seeing any of these, but I suggest taking a look at night. There were a few of these webs where I was camping in the Smokies last week, and when I checked on one in the dark, the spider was sitting outside its web, devouring a firefly. I had previously gotten a couple to peek out by tickling their webs with a pine needle--they came out enough to confirm ID of the spider, but not enough to get good photos. Nice to finally see these in person!
