Rio Bloodworm

A great midge pattern or searching pattern in dirt water 

Rio on their bloodworm:

Aquatic worms live in most bodies of water, so having some in your lineup is important. RIO's Bloodworm is tied on a unique hook that has proven to hold fish better than similar styles. The thin profile and durable coating help this sink quickly and stay in the zone, and it is incredibly easy to cast. You can fish this on lakes when fishing chironomids, as a dropper behind your favourite foam dry, under an indicator, or as part of your Euro nymphing rig.
