Salmonflies
Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

Moth Family Geometridae (Inchworms)

These terrestrial moths are sometimes taken by trout when their larvae, the well-known inchworms, dangle by their little silken threads in especially high numbers around June. They may be abundant enough throughout the forest that plenty dangle their way into the water.

Specimens of the Moth Family Geometridae

1 Larva
Geometridae (Inchworms) Moth Larva
I caught this inchworm lowering itself to the surface of a trout stream from its silk thread. I saw a couple others floating on the surface, so it's likely the trout were familiar with them.
