Description
BWO Split Case is a highly effective nymph pattern that imitates a Blue-Winged Olive mayfly in the critical emerging stage. It features a slim, olive-brown body and a prominent white split case that mimics the nymph’s wing pads just before hatching. This realistic trigger sets it apart from standard nymphs and convinces even the most selective trout to strike.
Perfect for use during or just before a BWO hatch, this fly is designed to ride just beneath the surface or drift mid-column, where fish often feed most aggressively. It’s ideal in slower runs, tailouts, and riffles—anywhere trout are keying in on emerging insects. Whether fished alone or as part of a two-fly rig, the BWO Split Case is a must-have for technical water and finicky trout.
