I'd say it's the mom for sure. She does look like she influenced the pattern quite a bit on those spider babies. You say she's a wild caught? Or captive hatched import maybe?

I'd try breeding her to a different male. She looks very interesting. Almost genetic banded like. She resembles a hidden gene Woma. (yes they do look very different from regular Womas) but I doubt that's what she is.

Has she produced any normals that look just like her? If there is a possibility that she may be a subtle morph, she may not be genetically compatible with spider?

I really have no idea. The only way to know is to breed her to a different male to find out what's going on.
