J:Son Sweden's Mayfly Nymph is a realistic imitation of the nymph. Good choice when trouts, graylings or rainbow trouts are in selective mood. Fish with traditional nymph tactic or use indicator to notice all takes.

As mayfly nymphs spend most of their time close to the bottom and only moves longer distances by swimming or drifting downstream when they seek food, accidently loose their grip or when they are about to hatch, it is a vise choice to fish an imitation close to the bottom when you can’t see any mayflies hatch. The nymphs are active all year a round and are of interest for the angler from spring to autumn.
