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.

This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

Just a big old caddis larva
Just a big old caddis larva
By Troutnut on April 13th, 2023
I revisited the Yakima to see if I could find any more nymphs of the species I suspect to be Ephemerella mucronata, which is new to these parts, so I can try to raise the nymphs into adults and confirm. I did catch a couple. I also found this big caddis larva and tested out some new techniques with my camera gear, with mixed results.
Closeup insects by Troutnut from the Yakima River in Washington
This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.
