Male spiders are often smaller than their mates. Sometimes the female may attack the male in order to eat him. Many American wolf spiders "sing" to the female to distract her and try and save themselves. The male spider Pisaura mirabilis of Europe makes himself safe by catching a fly, wrapping it into a silk parcel, and presenting it to the female, who eats it as they mate. He does this in the hope that she won't be hungry enough to make a meal of him.
