Search the largest single source fly pattern & species database in the world.
Our database contains thousands of fly patterns including mayflies, caddisflies, stoneflies, tricos, and midges. Each pattern includes detailed tying instructions, fishing techniques, and matching species information. Because IdentaFly does not sell flies, our search offers more of an experience like an encylopedia. You can search by fly name, species, or lifecycle.
