black-widow01Black widows are known for cannibalizing their mates, but this doesn’t actually happen all the time.

If she ‘spits him out,’ so to speak, he will keep placing himself there until she eventually eats him.

For instance, the ogre-faced spider weaves a net between its front legs and then dangles above places where prey are likely to pass through. By using its web like a net, it scoops up hapless prey.
