I like fireflies a lot. They don’t occur in Ireland and I first encountered them during a fortnight spent in Tuscany at a NATO Advanced Study Institute in 1993. I now associate them with summer evenings spent on the porch in Michigan with my in-laws., watching the kids try and catch the little blighters. This is by way of pointing out that Carl Zimmer’s piece in tomorrow’s New York Times is on fireflies and that he has also blogged on them. The latter includes this wonderful quote: “You can even play the male or the female, depending on your mood.” Indeed.
