I believe that HG Woma wobbles the same as the others. See if it does the head tilt deal, or put it upside down. Wobble should show up quick that way. I have spiders that pretty much only wobble at feeding time, but I can induce it in them if I want to. I had to learn a lot about it because I have BEL spiders and without a black light the only way you can know for sure it is spider is try to make it wobble.
