I’ve been wondering about the sex of my zebra jumping spider, and I don’t know at what point they display their dimorphism

Nothing actually changes regarding their chelicerae. The pedipalps of male spiders will become enlarged. Most true spiders will start to show dimorphism in the penultimate instar.

Yeah your right with other spiders but Male zebra jumping spiders have enlarged chelicere. But your probably right that it’ll happen in the last two molts.

I stand corrected, don’t do too much breeding with jumpers. I would agree probably around the same time the palps change.
