Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Arthropod Class Collembola (Springtails)
Collembola are actually a subclass of a class called Entognatha. They are the most common of the only six-legged arthropods (Hexapods) that aren't insects. Many Collembolans are terrestrial, but some live on the surface of their water, and they can be a supplemental food source for trout, especially young-of-the-year trout.
They rarely grow longer than 6mm or occur in trout streams in such numbers that an imitation with a fly is warranted, but they are interesting creatures.
