Fireflies or Lightning Bugs?

What do you call that summer bug that flies around and has a rear section that glows in the dark? Do you call them lightning bugs or fireflies?

I’ve always called them lightning bugs, but I guess it depends on where you grew up. For the most part, if you grew up west of the Rockies you probably call them fireflies, and those east of the Rockies call them lightning bugs.

It doesn’t matter what I call them…they make me smile.  I have such happy memories of chasing lightning bugs with my brother when we were young.  And every time I see one, I smile at the thought, and think of my brother.  He died quite a few years ago, so that makes those memories even more special.   So, to me, they will always be lightning bugs.
