Heres a big lady I had the pleasure of encountering... I tried raising the babies but they were too small for the pinhead crickets I ordered so I released them (I had wolf spider babies at the same time which took care of the crickets).







And yes they could crawl out of that KK... I had some cloth on top of it, I took that picture once I brought them outside and they started scattering.

THANK YOU!:worship: I've had the pleasure to encounter a female with a sac living in a hole in a log filled with rain water at camp. I managed to get a pic of her when she was out crawling on her log a few days before she made the sac. And I never managed to get a decent pic because I think I might've scared her and she went under a tangle of vines that was on her log and she was well camouflaged.

That was the only pic that I could get. I didn't get it developed yet because I didn't know which camera it was in but fortunately I found 2 of the cameras that I used last year one is done and the other one has 24 pics left that I plan to use for none other then taking insects and spider pics hopefully all will turn out decent and clear and that the bugs will cooperate.:D

And the reason why I think that the spider I saw that lived in the log was a Dolomedes sp. was because of these 2 reasons:

♥ It had similar markings to the ones in the first 2 pics

♥ Every time she was peering out from the water in the log with her sac I would try to catch her. Never did as she always jumped back into the water with her sac!

And one of the pics shows one in water so that's what got me thinking the spider that I saw was a Dolomedes sp. Can you tell me what method they use to stay underwater? I'm familiar with this one. Thanks! And nice photos!

I found large four Dolomedes tenebrosus that looked gravid this past month. Three laid sacs and one molted. The one that molted was slightly smaller than the others, maybe 3.5" leg span vs a 4" leg span.

Note how this Dolomedes tenebrosus egg sac has swollen. First picture is shortly after sac was created. Second picture is yesterday. Do all spider sacs do this? I am assuming the swelling has something to do with the spiderlings inside having hatched and are moving around, stretching out the sac and that an emergence is imminent.

sac looks alot bigger man yeah.just rehoused my hopefully gravid female.hey any idea on how to tell the difference between d.scriptus and tenebrosus?according to spiders of the eastern usa they are distinguished by dif genitalia structure but i guesse they both overlap the same habitats.i just ordered the book spiders of connecticut the other day so hopefully that will help figure this out.

Gee that is weird because the one I saw had a sac that was waaaaay smaller then this one. But the spider had similar markings to this one. I'm confused! :?
