Baby Spiders

Asked August 6, 2016, 7:15 PM EDT

Hi, My husband rescues spiders from poison where he works. We keep them in captivity. Well, one of our Wolf Spiders laid eggs. We have had her for a couple of months so I think she is not inseminated. How long before she realizes there are no babies? I feel so sad about this :(

Hello,

Do you know if your wolf spider was mature when she was rescued? (If she was quite large and has not molted since she was collected, she may have already been mature when captures). If she was mature, it is possible that she had already mated, and spiders are able to hold viable sperm for a very long time. So, there is a chance that the egg sac will still hatch. However, it is also possible that she is carrying around a non-viable egg sac. Wolf spiders carry their egg sacs under their abdomen. If your spider is not carrying hers and instead has left it on the ground, then she has effectively already abandoned it as non-viable. She should eventually stop carrying a non-viable egg sac, although how long this will take will vary greatly. It is also possible to gently remove the egg sac using tweezers when she is carrying it if you somehow think it is better to remove the non-viable egg sac from her? If you have had her for 3 months and this is the first time she has made an egg sac, it may be a signal of some change in her diet or environment, or sometimes she is nearing the end of her life span and is making one last attempt to produce offspring. Some wolf spiders can live for several years, although it is tough to know how old she was when you caught her. Thank you for saving her and caring for her!
