The most rewarding and intense adventures in my life have occurred during fieldwork. One time in Madagascar we were sitting under a tree in pitch black in the middle of the night waiting for an aye-aye to come out of its nest. Suddenly, out of nowhere, a mass of fireflies began to dance, circling round
in the air. The 25-minute natural fireworks show those fireflies put on was one of the most beautiful sights I have ever seen.
