Advertisement 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.
