According to the International Carnivorous Plant Society, the origin of the name is quite lurid. The Venus Flytrap was first studied in the 17th and 18th centuries, when societal mores were a bit more puritanical than they are today, and were somewhat obsessed by human urges and sins. Women in particular were often portrayed as temptresses, greedy for power. The botanists of this time apparently found a parallel between the trap of the plant -- capturing and digesting insects -- and certain aspects of female anatomy and behavior. Thus, the story goes that they named the plant after Venus, the pagan goddess of love and money.
