When the Coch Y Bonddu beetles start to hatch—usually in May and June—you’ll want this pattern at the ready. Short-lived but highly effective, these small beetles emerge from grassy banks and become a prime target for hungry Brown and Rainbow Trout.
This foam-backed version rides high and stays visible, making it perfect for dry fly fishing during a Coch Y Bonddu hatch. It’s a must-have seasonal fly for explosive topwater takes when trout are tuned in to these beetles.
