Drakes and "Masking Hatches"

Dave Wolf makes an interesting suggestion in his coverage of the frenzy surrounding the annual green drake hatch in Pennsylvania: watch for the concurrent hatch of smaller bugs that will often be the target of the bigger fish. “Last but not least be vigilant for a ‘masking hatch,’ a smaller sized fly like the sulphur that is hatching at the same time the drakes are. If you want to take a trout on a drake imitation, keep on fishing. If you want to take more trout and large trout, switch over to the smaller pattern.” In Pennsylvania’s Lebanon Daily News.
