Based on the original Orvis Caddisfly Handbook, this wholly revised
title is small and light enough to carry along for use on the water.
Caddisflies are as crucial a trout food as mayflies or baitfish, and any
serious trout angler needs to know these insects well. Detailed
descriptions and photographs of the major caddisfly species will direct
the angler toward correct insect identification and fly-pattern choice.
