Confrontation - Dysdera crocata

Confrontation - Dysdera crocata
Basking Ridge, Somerset County, New Jersey, USA
December 6, 2012
Size: 1 in
So here's what happens when two of these meet up. They tensely embrace each other in a tangle of legs. It seems like they're more attempting to figure out who's bigger/stronger than actually trying to kill each other, but I could definitely hear the sound of fangs grinding together. When they're finished (usually about 20-30 seconds later) they release each other and slowly back away, the losing spider's legs twitching. It's weird. Then they just sit there for a minute until they slowly back away from each other and go their separate ways.

Info page
I've placed this image on the info page. Thanks!

 
no thank YOU! But..
I'm pretty sure they're fighting, not mating... I could literally hear their fangs scraping together, and it seemed like they were trying to bite each other. Also, aren't they both females? I don't really know the difference for woodlouse spiders but they looked exactly the same to me...

 
One on the right
They might be fighting but it does look like a male & female. I'm guessing the male is on the right. I think I see enlarged palps on that one, but I could be mistaken. I'll change the info page wording just to be safe.

 
I added another picture
with 3 of them this time! The 3 biggest I've found. I thought that keeping a few as pets would help me get over my fear of them (imagine turning over a small rock and having your finger resting its face!). It didn't really help, but I guess its helped me admire them a bit more.

Anyway, the one on the left of this picture is to the right of the picture I just added. But I can't remember which one the other is.
