true spider hybrids?

[mrglock27]

Can different true spiders cross breed? I have a false widow (steatoda grossa) female and I threw in this other reddish true spider male into the jar for fooda couple months ago, now the false widow just hatched out like 30 spiderlings, she has been in the jar for 1.5 years with no other false widows. Thanks, Mike

Normally not. They have very complicated copulation organs. Maybe she was fertilized before you put her in there. You have also reddish Steatoda grossa males.
