The Summer Duck Pupa catches huge trout and bass. This simple fly pattern is a well-known and used fly in all of Canada and the United States. The red body imitates bright chironomids and Zinger Fishing suggests using larger hook sizes to land the bigger trout.
This fly pattern is typically fished in the summer months as the hook represents the pupa state of the chironomid.
We fish this fly with a few split shots to help it sink, and it is always under a strike indicator or rubber dry fly that can stay afloat. Pupae are feasted on by fish, so you will want to be fishing these hooks quite often.
