WD-40 (also called WD-40 Midge or WD-40 Emerger) is a slim, high-floating emerger/pupa pattern designed to fish tight in the film where midge and small emerger activity concentrates. Built with a thin foam or dubbing body, sparse CDC or feather wing, and a pronounced small trailing shuck, it rides low and horizontal in the surface film to imitate struggling or newly-hatched midges and pupae. Excellent for slow, clear-water midge fishing, it triggers finicky trout that reject bulkier dries — fish it dead drifted, with slight twitching, or as part of a tight-line nymphing tandem. Tied in size 18–26 and subtle earth or olive tones, it’s a must for lakes and calm tails where midges dominate.
