WHY DO LIGHTNING BUGS FLASH?
Flashing Lightning Bugs are trying 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.
