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.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

This midge and several like it, including a female I also photographed, hatched from larvae which were living in some fine mud I'm using as substrate in my bug-rearing aquarium.

This midge and several like it, including a male I also photographed, hatched from larvae which were living in some fine mud I'm using as substrate in my bug-rearing aquarium. This one flew away before I could photograph it on the ruler, but it would have measured slightly smaller than the male.
