Here in south-central KY we have TONS of lightning bugs! This year we've had more than ever. We litterally have hundreds of them in the yard every evening. We have some pastures around us that have hay (and weeds, lol) about 2 1/2 - 3 ft tall. The ligtning bugs must live all in that because every evening those fields just light up, there's so many lighting up at once that it's just a continual light four ft or so off the ground. Really incredible sight.
