Size: 10 Only.  A State Fish Biologist told me this was the most realistic egg pattern he has seen.  Hot Glue eggs work magnificently for trout, especially in turbid or off-colored water. Many anglers who fish tail water fisheries turn to egg patterns when the dam is releasing water. Egg flies are also remarkably effective for timid trout in spring creeks. For many anglers, an egg is their “go to” pattern when the fishing is slow.
