Can you tell if a lightning bug is a girl or a boy?

There are over 100 pecies of lightning bug or firefly. Different species of firefly have different flashing patterns so members of the same species can recognize each other from a distance. In most firefly species the males flash while flying and the females flash while perched on plants near the ground. When a male who is flying sees a flashing pattern that matches his species that is stationary and low, he'll fly over to it hoping to find a new girl friend.
