It is strange. I did not breed Bela to any other males this year, save for the Spider. I see what you mean about the genes not being able to combine in one baby from two seperate fathers though.
I do not think that this baby is a bee. It looks if anything, like a very light spider with a really reduced pattern. No darkening up yet since yesterday, but who's to say it won't happen.. I am waiting it out. At any rate it will be an awesomely patterned Spider if nothing else
