The Mr. Rapidan Soft Hackle is a great fly to use when the trout are taking emerging midges.
Many trout feed actively on the great number of chironomid midges which hatch at this time of the year. If you see a dimple rise they are taking the adults so show them a Mr. Raidan Dry Midge size 20. While you are fly fishing if you see splashy rises they are taking the emerging midges so fish for them with a Mr. Rapidan Olive Soft Hackle size 16 or a Brassie size 18.
A size 24 Dry Midge or pseudocleon can be difficult for some anglers to see on the stream which results in many missed strikes. An easy way to spot your fly is to place a 1/4 inch piece of an SA Indicator 3 feet up the leader from the fly. This is so small that it will not interfer with a smooth presentation of these small flies on a 6X or 7X leader. Yet this is easy to spot on the stream and it accurately guides your sight to the fly.
