1) almost 100% sure shes a Dolomedes tenebrosus.
2) shes a bit over 3 inches, 3.5"-ish
My D. okefinokensis that has been captive for awhile now just laid a dud sac too, so apparently it is kinda common among this genus. I'm now curious if this is occurring with other spiders in the family and not just the genus.Ive raised several D. tenebrous spiders and I have found that if you feed them well and they are mature they will make dud sacs. I have found it odd that the females do this but seems normal anymore. Ive also had Latros do this before as well.
This is my second of the species and both have done it when they got really fat. The first I had to take away because I knew it was a dud and she wouldn’t put it down to eat. The second I’m waiting to see if it’s fertilized because I she hasn’t molted since I got her a few weeks ago and I want to see if ITV hatches. I do tend to overfeed so that may be part of it as well.Ive raised several D. tenebrous spiders and I have found that if you feed them well and they are mature they will make dud sacs.
