For those of us searching for the answer to the most asked question in fly fishing. Which fly should I use? This book will offer you the simplest answer. Flowers bloom, and insects hatch in a trout stream, in the same specific order year after year. Just as Daffodils bloom before Tulips, Hendricksons hatch before the Green Drakes. The illustrated plants are the indicators of which fly to use. The hatching insects and the blooming plants are directly influenced by the same factors, light and temperature. The flowers illustrated were selected for their ease of recognition, and more importantly, because the blooming period coincides with the hatch of trout stream insects. As flowers are much more recognizable than insects for most of us, why not use the method that makes fly selection easy, and fly fishing more fun.
