    Hello,
    around 2 weeks ago I finally managed to catch my first jumping spider. I put her (I think it's a female, not sure though) in a small 20cm x 20cm x 30cm terrarium with branches and she was doing great. I gave her a fly every 1-2 days, which she gladly ate. She also drank water from droplets on walls.
    I'm not sure what species she is, as you might've noticed I live in Poland and I caught her here. It looks very similar to a zebra spider but her abdomen is all gray with no stripes. I haven't measured her size, but she was fairly big and I think she was about 10mm to a centimeter.
    The problem is, four days ago she made a nest in a corner of the terrarium in a hidey spot under a branch and hasn't come out ever since. I thought she was going to molt but I read it takes 1 day, 2 at most. Is this behavior normal? Is she gonna starve herself to death? I tried holding a fly next to the nest for a few minutes but she didn't care.

    If you caught her outside, she could be getting ready to make a sac :)

    Wow, I wasn't expecting this. How long does it take and will she live long after this?
    If that's the case I'd like to keep a few spiderlings and release the rest, can I keep them in the same terrarium?
    Aside from the sac, is there any other possible explanation? Because I'm not completely sure if this is a female.

    I am just keeping my first jumping spider, I only know that there is a chance she mated before you caught her. I'd wait for others to chime in on questions regarding breeding. Don't want to give wrong info.
    Another cause for her webbing could be she's getting ready to molt. The larger they get, the longer it takes to molt, including the pre-molt fase. My P.regius didn't eat for a week and hid herself in her thick webbing before actually molting. :)

    Was she plump when you found her? If she had a large/swollen abdomen, there is a very good chance that she is making an egg sac now. Jumpers will frequently remain inside their web nests, guarding the sac, until the babies hatch - and even after the babies hatch, they will sometimes hang out near the sac for further guard duties. The babies will also stay in or near the sac for a while and will retreat into the nest when they feel threatened. Of course, as they get older there may be considerable cannibalism, both between siblings and sometimes the mother will eat some of her young. If you want to keep some of the babies, wait until you see them leave the nest - then separate those you want to keep into their own deli cups and start offering fruit flies, aphids, or other small prey. Release the rest before they eat each other. Depending on her age, the mother may live for a while yet. I've had some jumpers that have lived for up to six months or more after making a first egg sac - sometimes even hatching out a second clutch of babies.

    She really could make an egg sac in September? :wideyed:

    I'm not quite sure what classifies as plump since this is my first jumping spider, but I think her abdomen increased in size while I was keeping her. Whether she's molting or making an egg sac, that's good news as I was worried there was something wrong with her. So I should just wait?

    Yes, just be patient. When "Pumpkin" (my female Phidippus nikites) was gravid, she got huge - more like a "waddling spider" than a jumping spider! - and then she disappeared into her little web nest for several weeks and emerged, if not exactly svelte, at least considerably slimmer and more maneuverable. After she laid her eggs she emerged a few times to eat, but she spent most of her time in the nest. Only after the babies had left the nest did she resume patrolling the enclosure and get back to her greedy, bug-munching self. (She's actually getting pretty round again - it would not surprise me in the least if she's working on a second egg sac.)
