Same as other spiders, BUGS!
they eat there mate
Yes; they eat their mates.
they eat insects and titty hair
Nope, not a chance. Those two species come from completely different families and they would attack and eat each other. I don't think it is even physically possible for them to mate. Mating pairs of individual species have genitalia that is pretty much a lock and key system. One perfectly fits the other. Other species' equipment simply would not work.... and like I said, these two species would instantly attack and eat each other before they even knew what hit them.
The Black Widow spider will mate, and then eat her mate because they are stuck together.
Yes in fact the only thing alive that can eat a black widow is a dog and cat because some thing about them can handle it but if anything else eats one they will die very soon so make sure if you have an animal don't let it eat one but if you have a cat or dog it's fine.
Because she's hungry. Most spiders are cannibals and will eat each other if the opportunity arises. However, the only Black Widow species where the female has been observed to eat its mate is Latrodectus mactans, the "southern black widow". And even in this species, it does not always occur.
