Nymph fly patterns are artificial flies designed to imitate the aquatic nymphs of various insects that fish feed on. They are a popular choice for fly fishing, especially in still waters or slow-moving rivers, as they can be very effective in attracting strikes. Here are some of the most popular nymph fly patterns:
Mayfly Nymphs (Copper John, Pheasant Tail, Hare's Ear, Prince & Zug Bugs), Caddisfly Nymphs (Caddis Pupae, Miracle Nymphs, Serendipity, & Zebra Midges), Sowbugs, Stonefly (Halfbacks, Standard & BH Stones, Pat's Rubber Legs).
