The Fly Trap is a memoir of a Swedish entomologist who specializes in a subset of flies. Don’t leave yet! It’s really quite entertaining, as a stream-of-consciousness diary of his life, the storied life of the inventor of the clever fly trap he uses (the son of a French immigrant to Sweden), and, most amusing, rantings about the silly ways of eco-warriors. And the kitchen sink, in this case the factoid that the author bought a house because the outhouse it came with had belonged to some 19th century bishop and poet. It is a two-seater, if you can picture that.
Fly collectors must have a lot of time on their hands as they lie in wait for their subjects. The result is a success, especially if you, like me, are always curious about other careers than the one you chose.
