I too love butterflies, but I do at times suffer a little because of his far greater (than mine) dedication to the cause. My DBH is small fry compared to your DBH, but he still works fulltime and is an athlete and a singer and has so many other hobbies that I can't keep up. I can quite see him getting more dedicated to it when he finally retires, though. I can think of far worse things that he could have felt like doing in his spare time.
