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. The hackle-less Comparadun has a low profile but floats well, which is an advantage on slow, quiet stretches of water.


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

How to Fish

Dress the fly with floatant and use standard dry fly presentations.
