Spider ID - Ariadna bicolor
Copyright © 2009 Scott Justis

Spider ID - Ariadna bicolor

Size: 3mm (body)
This is one of those little spiders that makes a woven tube in tree bark. Kind of like a trap door spider, without the trap door.

Moved from Ariadna. Based on range listed on genus page and the other web image.

Tube
Did the tube look anything like this?



I'm not sure about the eyes, though.

Cicurina bryantae...
...is what John is referring to. I just wanted to comment about the eyes. Spiders in the dictynidae family (which I believe this female belongs to) can have 6, 8, or no eyes at all. And the 6-eyed and no-eyed versions of the Cicurina genus live in caves in Texas and Alabama, so I personally don't think this one is a C. bryantae unless a tube retreat made of rotting wood was specifically what was witnessed...but this genus is referred to as the genus from hell by many an arachnologist...so who knows. :) (I know John already knew all this, so this was mainly for the submitter.)

EDIT: Although, I will say that the darkening (or freckling) of the abdomen and carapace is something that happens in C. bryantae as they age...so there's another thing to ponder.

John, Mandy...
Thanks for the help and info! The tube was mostly spun spider web as I could see through it. The bark was from a large dead maple tree.

Good call, Max!
I bet you just nailed the ID. I totally forgot about the segestriids.

Ariadna
I agree with Ariadna sp. The number of eyes (6) and their arrangement matches, as well as legs III being directed forward.
