None of my Spiders spin...I've bought some and I've produced some - None spin or wobble...They do get excited when it's time to eat but I wouldn't call that spinning...I produced 3 Bumble Bees this year - None of them spin...The female Bee that I kept back has what I call a "head tilt"...Nothing major - The only time she tilts (tilts slightly to the side) her head is when you pull out her tub...The male Bee that I kept back doesn't "tilt", wobble or spin - He feeds and breeds great though...LOL...I have seen pics of severe spinning in Spiders - I believe Cory Woods has the worst case of a Spider spinning that I have seen...I guess it comes down to - Some do and some don't but to say they all do is not accurate...
