Fireflies are interesting - as a New England kid in the 80s, I used to read about them in all sorts of childrens' books, but I was really bummed because I never saw one. I think I saw one firefly in my whole childhood. I just went back to Long Island this summer, and they were all over. It'd get to be twilight and hundreds of them would just be dancing through the air. I got to show my wife the childhood scene that I'd only imagined.

Maybe all the fireflies moved from Michigan to New York. I think I'd read somewhere that firefly populations tend to be very cyclical anyway though.
