Terrestrial insects are making for good action all around.   In particular, the spruce moth population is up and makes for great dry fly action on the Madison and Gallatin river drainages.   The Beaverhead River features good PMD and caddis activity, which along with terrestrial insects are bringing big fish to the surface.  Hebgen Lake gulpers seem to have active and inactive days according to report reaching us.
