Southwestern Montana
Spruce moths are beginning to show up in good numbers on the Gallatin River and soon will do the the same on forested sections of the Madison River. There are specific patterns for these insects, but any simulating a caddis fly ( elk hair caddis, X caddis, etc) work just as well. If you prefer fishing smaller, less crowded steams, check out the West Fork of the Madison River to see if these insects are active. Anywhere you find spruce moths present trout love them as a food form.
