The Adams is a well-known fly tied in a wide range of sizes. Used primarily to target trout, the fly is used in its smaller sizes to cover midge hatches and mayfly hatches. In the right size it makes a reasonable impression of a blue winged olive or other small grey/olive bodied ephemerid. Larger versions are serviceable in a drake hatch. The Adams is considered by many, a “go to” fly, and a very useful searching pattern.
How to fish:
Fished using standard dry fly presentation techniques. When no specific insect predominates on the water and it is not clear what the fish are feeding on, a well presented Adams is a good way to hedge your bets.
