Bumblebees do brown out some, but if your picky and make sure to get one that comes from beautiful adults then your probably more likely to end up with a beautiful adult.

This girl has browned some but not too bad, she comes from NERD and is a Lemon Bumblebee. (In Glow)


That led to this...


Which should lead to 7 fertile eggs very soon, looks like her ovy is finally starting

The wobble issue is so individual, this girl doesn't even tilt her head sideways like most will do, no wobble and no corkscrewing.

Our spiderbelly girl does some very light headshaking when honing in on her prey but otherwise has a very stable head.

Our male spider is a train wreck and corkscrews and wobbles as bad as any spider I've seen.
He was perfect for 8-9 months but from then till now has steadily gotten worse. He is almost 3 years old now and has a rough time finding his prey item without striking at everything else around him.
I've decided not to breed him, just don't see the point.
