Violent sex is taken to an extreme in warehouse pirate bugs, where the male uses his daggerlike penis to break though the female's body wall and insert sperm directly into her abdomen. Now researchers have found that after enduring bouts of traumatic insemination, the females live fast and die young. Those female warehouse pirate bugs take advantage of what life they have left and produce more eggs quicker than other pirate bugs. Though the warehouse pirate bug may be able to mate normally inserting the penis into the female's reproductive tract , they seem to have ditched this for the traumatic type of mating, Cameron said. That's a seemingly odd choice, since dagger-penis mating is dangerous: Traumatic insemination leaves gaping, seeping wounds on the female. The researchers wondered if this dangerous mating habit affected the female's life span or reproductive ability.

The main reason Lightning Bugs flash is to attract mates. Among most but not all species of North American Lightning Bugs, males fly about flashing while females perch on vegetation, usually near the ground. If the female sees a flasher and she's ready to mate she responds by flashing right after the male's last flash. A short flash dialogue takes place as the male flies closer and closer, and then, if all goes well, they mate. So that a flasher doesn't attract a firefly of a different species , each Lightning Bug species has its own special flash pattern.
