hello i have a juvenile bold jumping spider that went into premolt about a month and a little bit ago, almost a month and a half now. i know they can be in premolt for a long time but im getting worried bc of his strange behavior lately. hes for sure getting hungry, his abdomen is getting small enough i can see the outline of his guts, but hes still not ready to eat. i cant really tell if he wants to eat though because every now and then he will venture out of his hammock and be very active circling his enclosure and watching the substrate. he has red springtails in the substrate, and ive offered him mini mealworms in a cup as well as fruit flies (he successfully has eaten both in the past.) today he was really concerning me. the past 2 days hes spent all day pacing his enclosure and watching the dirt, and today he did the same but this time he was moving way faster and seemed to engage in hunting behavior but backing out and going back to running in circles around his enclosure. should i be concerned? i think im going to make adjustments to his enclosure to retain moisture a little better in hopes that that helps him molt but im getting really concerned by his behavior. he needs to either molt or eat so he can get on with. either eating or molting, u know? is there anything i can do? is over a month too long to be in pre-molt? because the only info i can find is that up to a month or weeks at a time is normal. should i be concerned by his behavior?

Unless he's a very small instar, springtails may be too small for him to eat enough of to gain weight. He may not be recognizing the mealworms as food. Try a baby cricket on the enclosure floor, just a little smaller than the whole spider minus legs. Mine has done very well with larger prey items when he's hungry. Or you could try leaving a handicapped mealworm (crush the head) on the floor, seems like he's looking for food down there. Mine love houseflies, you can buy larvae online.
