Wow! What character trait leads you to believe there are more males? Fenakes have the rounder abdomens and males are more elongated? I may have a hatched sack also, my female Wolf spider spun a sack shortly after I found her, only it looked a bit unhealthy, it seemed discolored and shriveled. Well about two days ago there is a tiny spider running around in her enclosure, I don' know if it is possible for only one to have survived, or if it could have are the others, I will be posting a pic in the gallery for I'd of the little guy. It could just be a hitchhiker who came along with pieces of log in her enclosure, but I really do hope it is her lone spiderling! Will update you! Also, how do you keep them away from the top of the jar?
@Dawnes1221 yes the females have a much more symmetrically round abdomen compared to the males which has a more oval shaped abdomen that is much thinner and not so bulbous. Keeping them from reaching the top is a challenge I am using petroleum jelly to somewhat keep them from the top so I don't damage their webbing but it does not work as well as I was hoping bigger spiders most certainly get to the top still but they do not stick their web to the petroleum. Which makes it easier for me to open the lid and return the ones at the top back into the tank. But dealing with widows I have to be very careful not to drop any when I open the lid. Also do you have a way of getting the egg sack from your wolf spider if you can shine a light through it to see if any eggs are present and look for holes in the sacks if there are any holes or tears. If there is a big dark cluster in the sack when you shine the light through and no holes in the sack they are probably almost here.
@Daniel0430 I heard if you put a light or flashlight shining at the bottom the spiderlings will gather to that spot, also in the video where I heard that, they also advised putting the nursery container on a baking sheet with poison (bug spray/bleach/pesticide?) So if one to were escape when you opened the lid, it would have to cross a deadly moat, killing the spider but at the same time protecting your home from any escapees. Don't know if that would be helpful or harmful and trouble maintaining it. Also, I believe it has been over two weeks since she abandoned her egg sack and I haven't seen it, but will look for it and try your suggestions if I find it and let you know what I find! Most likely it was not viable, but I am hopeful!
