Casual dating can be dangerous — a study of spiders shows female
wolf spiders will eat strange-looking males that try to mate with them,
but spare and even hook up with familiar-looking males.
"The female is using earlier experience that is going to affect her
mate choice later," Hebets said in a telephone interview. "It
is reasonable to expect that is a common thing in other animals."
Hebets worked with Schizocosa uetzi spiders, commonly known as wolf spiders.
They have an elaborate courtship ritual in which males arch their brown
or black forelegs and vibrate their bodies.
