Book excerpt: In lively, accessible prose, John Himmelman explains the intricacy of moths' life cycle, their importance in nature, and how just a tiny handful of the many moth species are truly pests to humans. He tells how to attract moths with lights and bait, when and where to observe them, and how best to photograph these tiny subjects. Entertaining personal anecdotes and short profiles of some of the country's foremost moth-ers add human interest. This new edition updates photos and information while focusing on states east of the Mississippi.
