Comparaduns are useful, durable patterns that imitate the dun stage of mayflies. Use them during a hatch when duns are on the water and are being taken by trout.

Comparaduns ride well and float without hackle, which is an advantage on slow, quiet stretches of water. The pattern is more durable than a No Hackle, but it's not as effective on spring creeks.


Other mayflies can be imitated by using hook sizes and body colors that match the natural insect.
