I worked with a guy from Germany about 20 years ago, before it was as easy find this sort of information online. I asked him if they had fireflies in Germany and he kind of scoffed and told me "Of course we have them over there!"
He didn't know, at the time, that they were extremely rare starting somewhere west of the Mississippi river.
I suppose it's west of the Mississippi, but it's a long ways west. I'd imagine it's around the 100th meridian then. That goes through the middle of Kansas and is where you start to expect to see more western species as you travel west past it and vice versa.
