The Hare’s Ear Hot Collar is a popular variation of the classic Hare’s Ear nymph, featuring a “hot spot” collar, often made with a bright color like fluorescent orange or red thread. This hot spot creates a trigger point, attracting attention from trout and enticing them to strike, especially in low visibility conditions or in faster water. The collar can also be made with other materials like ice dubbing or CDC (Cul de Canard) feathers for added movement and lifelike qualities.
