Harrop’s CDC Biot Emerger BWO – Solitude
When trout key on Blue Winged Olives just before they break the surface, few patterns are as effective as Harrop’s CDC Biot Emerger BWO. Designed by René Harrop, this fly perfectly imitates BWOs in their most vulnerable stage—emerging in the film—when selective trout often ignore fully emerged duns.
The slim biot abdomen creates a realistic, segmented profile, while the CDC wing provides subtle flotation and a lifelike footprint that sits low and natural. This combination lets the fly ride in the surface film, not on top of it, making it deadly during cold-weather and overcast BWO hatches when trout feed with precision.
Fish it solo to match the moment, or trail it behind a small dry for a highly effective dry-dropper or double-dry setup.
