Vince Marinaro, author of the pathbreaking A Modern Dry-Fly Code, and other noted Pennsylvania anglers like Charlie Fox, Ed Koch, and Ed Shenk explored and promoted the advantages of terrestrials during the summer months. Their efforts helped bring crickets (and grasshoppers) to the attention of fly anglers in the 1950s and '60s. Crickets seldom dominate a particular forage base like grasshoppers do in August and September, and that may partly explain why they have remained in the flyfishing shadows--even today. Their availability extends over a larger area, however, and a longer period of time. Trout eat them all summer, and no doubt the early-summer success of size 12 and 14 black nymphs and wet flies has something to do with the number of small crickets that find their way into trout streams.
