My male spider eats like a garbage disposal. He's also a funny guy. He likes to lay with his head turned sideways and he'll corkscrew in the air when handled.
My female bumblebee is a picky eater. She will not eat unless she's in her hide with her head poking out, and you haven't disturbed her in any way the last 1-2 days. When I first had her in a 6 qt tub (no hide) she wouldn't eat at all. I made her a ghetto hide (out of cardboard) and she started eating. She does not appear to have any symptoms of wobble. Her strikes are always very precise and she doesn't shake when preparing to strike. I don't hold her much because she stresses easily so I dunno if she dances in the air.
