I grew up (in S.C.) calling them lightning bugs- but now I call them fireflies. I wonder at which move that happened? *ponders this*
Whatever one calls them, they actually frighten me with their beauty. I remember once, at Lutheran camp, the other campers were singing and I was a little ways away from the campfire. On one side, I could hear them singing, and on the other, I saw the beautiful floating fires, turning the nearby forest into a faery-land with their light. I felt myself getting up to follow them and actually had to physically stop myself. They speak to me on some level of spirit that is more primal to me than human.
