“Young . . . brings the trained eye of an entomologist and an unabashed admiration for the beauty of nature to this engaging and informative account of his experiences during twenty-one years of fieldwork in Costa Rica’s rainforests.”—Publishers Weekly

“A splendid read. For newcomers to the moist tropics, and for any but the most sated old-timers, it can be commended for an entertaining account of a locality where life is lived to the full—by all species, including the human observer.”—Norman Myers, New Scientist

The abundant insect life of the rainforests of northeastern Costa Rica is the subject of this engaging book, first published over twenty-five years ago and now including two new chapters on the rise of ecotourism in the region.
