The common stream insects are dimdamflies, Blepharo- cerids, mountain midges, Stoneflies, etc.
The streams fed by the melting snow and
ice are inhabited by the larvae of mayflies, Stoneflies, caddisflies and dipterous flies.
The foothills and the wooded slopes of the higher mountains are
populated by a great abundance of insects of all sortsmayflies, Stoneflies, grasshoppers, crickets,
dragonflies, caddisflies, bugs, cicadas, beetles, ants, wasps, butterflies, moths, midges, gnats, mosquitoes, etc.
As a an entomologist who has studied Stoneflies and mayflies for over 40 years, I have discovered
these insects have value far beyond luring trout- they are indicators of water quality in streams and are a crucial piece of the larger food web.
