On a related topic, while in New York Botanic Garden last summer B watched the outcome of a fight between a pair of dragonflies. At first they seemed to be dead, but the victor was laying on its back, having bitten the head off it's opponent, and was chewing away at the still twitching corpse. After a couple of minutes, and a few photos, he touched the insect to see if it was injured and it flipped over and flew off. Donald seemed like an appropriate name for this pugnacious New Yorker.
